In Perth at the moment we are heading towards summer and believe me when I say in Perth we get a summer big time ! Living in what is essentially a desert does have it’s advantages. For nine months of the year I consider the climate to be just about perfect for running. A reasonable temperature with little humidity and even less rain. When it does rain it feels like a warm shower compared to the horizontal ‘take out your eyes’ sleet I use to experience in the Scottish summers I came from. (Apparently it’s worse in winter but I never found out as it was too dark , too cold and too damn dangerous to ever wonder outside.)  When Summer does arrive you can still run in good conditions you just need to adjust your day. You need to awake at first light and race the sunrise before the Perth sauna is turned on and anyone found outside understands what it feels like to be cooked in a microwave. If you’re lucky you may get a reprieve in the late evening but when summer comes a calling you may only get that small pre-sunrise window of opportunity.

Runners though like to run and not be dictated to by temperature or season, thus sometimes they just put on the trainers regardless and brave the elements; after first bathing in suntan crème. When you are faced with anything over 30c it’s time to rethink your run. Pace needs to go out the window and in comes survival and damage limitation. Believe me I’ve been there when you’re halfway through a 10k loop and suddenly realise you’re dehydrated and the body has had enough. It’s not pleasant and it always happens when you are at your furthest from any help. (Funny that?)  It’s at times like these you need to just knuckle down and plough on, albeit slowly with walk breaks if needed. The most important thing is getting back to the start in one piece without doing to much damage, both mentally and physically.

So what’s the answer ? Running in the heat can improve your running and even make you stronger but there are certain aspects of your run that need to be adapted.  As well as running slower you must also be fully hydrated, common sense I know but still worth highlighting. This hydration process is also best started the day before the run and continued up to the run and while running, and of course afterwards. Basically drink, a lot ! I would also recommend electrolytes rather than just water , it all helps.

For me in Perth at the moment I’m out the door and running by 4:50am and although that may sound early the rewards so outweigh the early start. I get to see the sunrise every morning and also enjoy the solitude of the early morning. Everything is so much quieter and you really can bask in the new dawn. The downside of course is after I put my nine year old to bed I scuttle off to my bed myself to eagerly awake my alarm informing me I get to race the sunrise again . My Wife , who luckily is a night owl, gets her ‘Karen time’ so all is good in the Matthews household. (Spending too much time with my Wife always put a strain on the marriage. That was a joke by the way.!)  So for summer move your waking day to the left and rise early, enjoy the morning before sneaking off to bed while most people are sitting down wasting their lives watching rubbish on TV and eating ‘crap’. You know it makes sense, I’ll see you out there.

Footnote. I took my own advice for a change and rather than put myself through the sauna that is lunch time running I waited until the evening and ran a pleasant 10k racing the sunset, after racing the sunrise this morning. Both glorious runs for different reasons and so much more pleasant than a lunch time run when I would have been battling the higher temperatures and returning to work looking I’d been swimming while wearing my work clothes. So, as pointed out in the articles below, you just need to choose your time wisely when it comes to running in heat, best to avoid it really but if it is unavoidable make the best of it. 

I have found two great articles below that explain how running in the heat can help to improve ones running and with the right tweaks can also be as enjoyable as running in normal conditions.

One of the highest sweat rates ever recorded was that of marathon runner Alberto Salazar at the 1984 Olympics in Los Angeles. In the months leading up to the games, which were expected to be oppressively hot, the marathoner was put through a regimen of temperature acclimation training with the goal of helping him adapt to running in the heat. While Salazar placed only 15th overall, the program was deemed a success, physiologically speaking—vitals taken after the race found that Salazar’s hormonal and thermoregulatory systems were completely normal. His body had compensated by causing him to sweat at an incredibly high rate—about three liters per hour, compared to the roughly one liter per hour for an average human.

Researchers have been looking at the effects of heat on athletic performance for decades, and their results have been consistently surprising. Studies have found that, in addition to an increased rate of perspiration, training in the heat can increase an athlete’s blood plasma volume (which leads to better cardiovascular fitness), reduce overall core temperature, reduce blood lactate, increase skeletal muscle force, and, counterintuitively, make a person train better in cold temperatures. In fact, heat acclimation may actually be more beneficial than altitude training in eliciting positive physiological adaptations, says Santiago Lorenzo, a professor of physiology at Lake Erie College of Osteopathic Medicine and a former decathlete at the University of Oregon. “Heat acclimation provides more substantial environmental specific improvements in aerobic performance than altitude acclimation,” he says. And in contrast to the live low, train high philosophy, we more quickly adapt to heat stress than we do to hypoxia. In other words, heat training not only does a better job at increasing V02 max than altitude, but it also makes athletes better at withstanding a wider range of temperatures.

Athletes can adapt to heat in one of two ways. The first is through incremental improvements in tolerance over time—work out in the heat a little bit every day, and eventually your body will dissipate heat more effectively. The second way is through thermotolerance, which is a cellular adaptation to an extreme heat experience, like suffering such severe dehydration after a run that you need an IV. Essentially, if you shock your system, your body will be able to withstand greater temperature stresses later on. But successful heat adaptation is difficult—and clearly dangerous—to achieve outside of controlled settings. Lorenzo explains that performance gains are possible only when athletes elevate their core body temperature, and without careful monitoring, it’s possible to elevate your core temperature to lethal levels.

When performed safely, however, heat training can have extraordinary effects. This phenomena fascinates Chris Minson, a professor of human physiology at the University of Oregon, who studies heat acclimation responses in athletes. According to his research, heat training can expand blood plasma volume, but Minson says there also seem to be inexplicable changes to the heart’s left ventricle, which helps to increase oxygen delivery to the muscles. In addition, he says that athletes who train in warm temperatures generally get better at regulating heat by sweating earlier, as Salazar did, or developing a colder resting body temperature.

A 2011 study by a group of researchers in New Zealand also found that overall volume of blood plasma increased at a greater rate when athletes did not drink water during exercise. While some coaches are carefully experimenting with dehydration, Minson and Lorenzo are not because it adds too much additional stress. However, they do say that this type of training can be beneficial because it produces a higher number of “heat shock” protein cells.

Ahead of Western States this June, ultrarunning coach Jason Koop worked on heat training with Amanda Basham and eventual winner Kaci Leckteig. Koop believes this type of acclimating is a good example of blending an academic concept with real-world training. But, says Koop, “at a certain level, you have to compromise training quality for the heat acclimation. Acclimating to the heat is additional stress [on the body], just like more miles or intervals, so you can’t simply pile it on. Something on the training side has to give.”

One method of heat acclimation that Minson uses with his athletes is to do hard workouts on colder days or earlier in the morning, and then start training in hotter conditions with less intensity. He is also looking into adding heat in ways that wouldn’t require an athlete to train in high temperatures at all—using hot tubs, for instance.

All this being said, not everyone responds to heat at the same rate or with the same physiological gains, which makes it similar to altitude training in that it might make a high-performing age grouper, college athlete, or elite a little better, but it won’t compensate for intelligent, consistent training.

How to Incorporate Heat Acclimation into Your Training Schedule

When acclimating to heat, you’ll be forced to compromise training quality, says Koop. While he understands the benefits of heat acclimation, he still prioritizes smart, solid training. But if you want to incorporate heat into your workouts, here’s how he recommends doing it safely.

1. First, pick a protocol (sauna, hot bath, or exercising in the heat) that minimizes the impact on training, both physically and logistically.

2. Koop most commonly recommends that his athletes use a dry sauna immediately after running. “It doesn’t impact training nearly as much as running in the heat, and the effects are similarly positive,” he says. He often tells his athletes to not drink water during these sessions to enhance the effect. Koop recommends spending 20-to-30-minutes in the sauna, depending on tolerance.

3. Koop says that when he has his athletes exercise in the heat—either naturally or by wearing extra clothing to simulate the experience—it will be on a long, slow day for 60 to 90 minutes. The time completely depends on the athlete’s tolerance and previous experience. But he stresses to not do this on a recovery day, because heat training is an added stress on the body. Koop recommends drinking 30 to 40 ounces of an electrolyte drink per hour during these sessions  And for safety, he advises using low-traffic sidewalks and bike paths—not trails.

4. Despite the benefits of heat training, Koop reminds his athletes that running in the heat is extremely difficult and usually replaces a hard day. “You are substituting one potential gain for another one,” he says. In other words, use it carefully

One more article , this time by Jason Fitzgerald from Strength Training. ( http://strengthrunning.com/about/ ) A great read.

Summer training ain’t easy. With skyrocketing temperatures, high humidity, and scorching sun it can feel like it’s impossible to get in a good run.

A long run or fast workout is hard enough. What about a RACE? Like a friend of mine always says: In the heat, I don’t compete!

Even if you just run easy and skip the hard workouts, how are you even supposed to just feel good when running in the heat and humidity of summer?

In the last few weeks, the runners I coach have said some funny things about running in the heat. My favorite:

“I just got back from my 8-miler, and it was BRUTAL. I couldn’t do the workout… my body just isn’t ready for 90 degrees “feels like 95” at 6pm. I just tried to repeat to myself “I LOVE SUMMER!” while also being glad I wasn’t jumping over piles of snow.”

Training well through the heat and humidity of summer takes a careful approach that combines timing, gear, and an understanding of why exactly it’s so damn hard to run in the heat in the first place.

But of course, it will still be tough. A few weeks ago at the Heartbreak Hill Festival put on by Runner’s World, I was talking to another runner about a race she ran in Miami. She was lucky to meet Kara Goucher and Shalane Flanagan (two pro distance runners), who told her: “I’ll take running at altitude over running in Miami any day!”

Even the pros hate summer running!

Instead of complaining about how difficult it is to run in the heat, let’s see how we can make the best of it. And maybe even make the fall our fastest season yet.

Why is it So Hard to Run in the Heat?

If you’ve read Christopher McDougall’s fantastic book Born to Run, you’ll remember that humans are amazing endurance animals for a host of reasons. We have:

A huge Achilles tendon that produces a significant energy return while running.

A (mostly) hairless body and highly evolved sweat system

Big butts. I cannot lie: according to Harvard professor Daniel Lieberman, our glutes are “running muscles”

A special ligament that attaches the spine to the skull and keeps our head from bobbing as we run

Can you guess which adaptation here is impacted by running in the summer? It’s our incredible sweat system.

Perspiration helps cool us off because as our sweat evaporates from your skin, it takes heat with it. But when humidity rises, it reduces your body’s evaporation rate because there’s already so much water in the air. Soon, you feel overheated and have to slow down.

If you live in an arid place like Colorado where the humidity is low, a hot summer day can still wreak havoc on your training for two important reasons.

First, the dry air evaporates sweat from your body almost as quickly as you’re producing it so you can become dehydrated much more quickly. If you start a run slightly dehydrated or run long without any fluids, your performance will significantly decrease (and you’ll feel like death).

As you become more and more dehydrated throughout a run, your heart needs to work harder to pump your blood because it’s becoming thicker (among a few other reasons too). This is called cardiac drift: your heart rate increases over the course of a run even when the intensity stays the same.

Let’s not also forget the heat and sun, both of which increase your core body temperature. As soon as you start getting too warm, running will feel much more difficult. Your “Rate of Perceived Exertion” (RPE) will increase even if you’re running a pace that’s usually comfortable.

Less evaporation because of higher humidity levels, increased chance of dehydration, and a higher core body temperature means that you’ll have to run slower to maintain the same effort. An unfortunate reality of summer training.

The Dangers of Running in the Heat

This article isn’t meant to scare you. After nearly 16 years of competitive racing and running in the heat and humidity of New England and the mid-Atlantic states, I’ve never been seriously affected by the heat in any meaningful way. Neither has any of my teammates in college and high school – and we raced and ran very tough workouts in brutal temperatures sometimes.

But that doesn’t mean the dangers aren’t real. If you run too hard at noon in July, you might experience some type of heat illness. Here’s what you need to know so you can avoid these setbacks.

Heat Cramps: muscle spasms that are caused by large fluid and electrolyte losses from sweating. They can occur while exercising but also hours after your run. No need to worry, they’re not serious – but make sure you stay hydrated and get enough electrolytes with sports drinks or fruit like bananas.

Severe dehydration: we’re all familiar with dehydration. Up to a 4% loss in fluid levels from exercise is still safe, but any more than that and you may experience dizziness, fatigue, and even mental disorientation.

Prevent this level of dehydration by starting your run already hydrated (your pee should be a straw color) and replacing your lost fluids as soon as you finish running. You can figure out exactly how much fluid you’ve lost by weighing yourself before and after a hot run.

Heat Exhaustion: if you work out too hard in the heat, you may come down with heat exhaustion – a case of dehydration, headache, nausea, and a core body temperature of up to 104 degrees. It’s much more common in runners who aren’t adapted to the heat.

If you think you have heat exhaustion, stop running, get out of the sun, and cool down with a cold drink and preferably air conditioning. And next time, run earlier in the day!

Heat Stroke: Danger! Heat stroke is very serious since your core body temperature is probably over 105 degrees. Symptoms include disorientation with clumsiness, confusion, poor balance, and a lack of sweating. Immediate medical attention is required where you’ll be cooled with a cold bath, air conditioning, and cold liquids.

At the 1978 Falmouth Road Race, Alberto Salazar (two-time winner of the NYC Marathon) suffered heat stroke and collapsed at the finish line after fading to the 10th place. He was rushed to the hospital with a temperature of 107 (!) degrees and read his last rites in a tub of ice water. He recovered and went on to become one of the greatest coaches our sport has ever seen.

7 Tips to Beat the Heat

The heat of summer isn’t the time to run your hardest workout and biggest mileage weeks – unless you’re super careful.

Run by effort, not pace. Running in the heat is the perfect opportunity to work on the skill of running by feel. Instead of strictly following pace targets that you might normally follow, run by time and effort rather than distance and pace.

Run early. There’s no perfect time to run in the heat of summer. But the early morning hours offer the lowest temperatures and a break from the strongest hours of sunlight (even though the humidity will be at its highest).

Get off the roads! Asphalt and concrete absorb heat and radiate it back onto your poor, wilting body. The summer months are a good time to try more trail running. Bonus: you have to run a little slower on trails which will keep you slightly cooler and trails are usually shaded. Win-win.

Adjust your expectations. If the National Weather Service issues a heat advisory (when the Heat Index, a score that reflects a combination of both heat and humidity, is over 105 degrees) running fast or long will be difficult and dangerous.

Even if there’s no heat advisory, remember why it’s so hard to run like you normally do in summer weather. Maintain the same effort and don’t sweat the slower paces (see what I did there?).

Don’t wear dark colors or cotton. Gear matters in extreme conditions so dress appropriately! Synthetic fabric like polyester is used in most running gear these days – use it.

Start your run hydrated (and keep hydrating). Even though hydration has been overemphasized in the last decade (see Waterlogged by Dr. Tim Noakes), it’s important to hydrate well before and after your run. Unless you’re running more than 75-90 minutes, you probably don’t need to take any water with you. But learn what works for you.

Plan your run around water. I never carry any fluid with me on a run – even a 20 miler in the summer. Instead, I run by fountains in public parks where I can swig some water and stay hydrated. If you live in a dry climate, running through sprinklers can help you stay cool, too. And who doesn’t love frolicking through a sprinkler?

Running in the Heat Has Its Advantages!

With all the whining we do about summer training, it actually makes you a better runner. Running in the heat causes our body to acclimatize to the conditions and adapt:

Your body gets better at sending blood from your core to your skin, helping to dissipate heat

With all that blood rushing to your skin, your muscles now get less oxygenated blood. So to compensate, your body produces more (who needs blood doping?!)

The body learns to control its core temperature and it won’t increase as much after you’ve acclimatized

You start sweating sooner at a lower body temperature to improve the cooling process

Sweat contains less salt so you maintain the right electrolyte balance

All these adaptations improve your efficiency and make you ready to run even faster as soon as the heat and humidity drop in the fall. So embrace the heat and run through it!

Then again, there’s some evidence that suggests that summer training is difficult because you think it will be difficult.

Yeah, tell me that after I shuffle home from a track workout in the sun and I might throw you out of my living room window.

But, it’s useful to know that at least some of the drudgery of running in the heat is because of our brain. It may present a good opportunity to “train your brain” to be comfortable being uncomfortable.

When you do, you’ll be in a good position to run a lot faster this fall. Take advantage of the physical AND mental adaptations you’ve gained from a summer of uncomfortable running.

You might just surprise yourself at what you’re able to run in a few months

My friend Nic Harman turns 21 today and what better present than a post about reaching your true potential. (Actually Nic would probably prefer hard cash but blogging does not pay the bills….)  I first heard of Nic when he won the inaugural Carine Glades Park run in June 2014 in a time of 16:58, with my mate Steve ‘Twinkle Toes’ McKean second a few seconds behind Nic. Funny thing was Steve reckons he was catching him, if he was that was his one and only chance because now Nic is running over 2 minutes quicker. In-fact a few weeks ago at another local parkrun Nic ran 14.53 for the 5k. That is now seriously rapid. Unfortunately ‘Twinkle Toes’ had his one and only chance to beat young Nic and blew it.

Since 2014 Nic has been working with Raf Baugh, the owner and coach supreme from The Running Centre ( http://www.therunningcentre.com ) and under his tutorage Nic took out the Western Australia State 10k title a few weeks ago setting a blistering time of 30:11 and beating the long term WA Athlete of choice Dr. Roberto Busi into second place by just over 10 seconds. Roberto has been the main man in WA for many years and this was a PB run for him , which considering he turned 40 recently is very impressive.

What I believe has set Nic apart from the many young talented and quick runners out there in WA is his ability to work with a great coach and follow instructions. Raf has big plans for Nic and Nic has an unwavering obedience that allows Raf to mould him to be the runner he believes he can be. Add in a work ethic that is just about as strong as imaginable and you have all the making of a future Australian champion, and then who knows.

As well as being a very talented runner Nic is just about the most humble person I know. Whenever I talk to Nic I always come away thinking that conversation was one sided with Nic listening and offering encouragement at all the right times and actually taking an interest in what I was saying. Maybe I’ll get Nic to spend some time with my Wife (That was a joke by the way…) Funnily enough the most talented runners are normally the most humble while the normal runners start blogs, that may not have come out as I hoped it would. Even I’m confused now and I wrote this paragraph. To sum it up Nic is talented, hard working and humble. These three attributes , together with a good coach, will ensure success. There you go, got there in the end.

So what can we take from Nic’s meteoric rise to eventual superstardom. One of Raf’s favourite quotes is ‘be your best’ and we can all live this manta if we choose to. The early mornings, late evenings, double up days when you’re fatigued or at the end of a threshold when your legs are screaming. These are times when you will be challenged and these are times when you need to step up and  ‘be your best‘ . I’m not suggesting we’ll all ever run as fast as Nic but we can run to the best of our ability and leave nothing in the tank, that is what being your best is all about. Finding your limit and getting to a point where you feel you can’t take one more step, then taking one more step.

How do we measure our goals and set ourselves targets ? Through past experiences and achievable targets. Once we have our targets we then design a training plan to achieve these. This is when a coach can help but if you cannot find one for ,whatever reason, it is up to you to draw upon your experience or from a more experienced running friend. (We all have them.) Then set about putting in the hard yards to achieve your goals and ‘be your best. ‘  Targets can be finishing a certain race, achieving a certain time or just running a certain weekly distance. Each of us sets our own targets and with hard work and determination you will achieve them, who knows maybe next year you’ll be sitting behind Nic Harman running the WA State 10k feeling you have him in your sights, a bit like ‘Twinkle Toes’ in 2014, if you do you better be prepared for a battle……

I was reflecting on my up coming 50th birthday today and discussing with my ‘pod buddies’ at work  whether my best days were ahead of me or behind me. My colleague Rob then added “it depended on which way you were looking.”  This really struck a cord with me and on my lunchtime 17k around the bridges (which in a Perth spring was a wondrous run.) I digested his comment. Rob had summed up why, as runners, we do what we do. Each of us ,I believe , through running, is looking forward and sees their best days ahead of them whereas the general public, when they age, turns around and sees their best days behind them. This is a powerful vision and it certainly made my 17k run disappear in the blink of an eye as I devoured Rob’s  insight.

Rob has totally encapsulated what makes us runners tick as we age. I have been lucky enough by putting in the extra hard yards and following my ‘Golden Rules’ (Remember those, if not there is a category for them on this blog) to be able to lay down some running times I thought beyond me. By looking forward to my best days I was achieving goals that seemed impossible a few years ago. Changing my training with the help of Raf from the Running Centre in 2015 ( http://therunningcentre.com.au/ ) had laid the foundation for 2016 and hopefully beyond. As Raf always use to say to me ‘age is just a number’. At the time my confidence was low and I took this onboard but didn’t really believe it totally. Now I am more convinced. I understand that eventually ‘Father Time’ will come calling and start to eat away at my times and I will be dragged kicking and screaming back to the pack , but with good training and hard work I will try my best to make it a slow transition.

As we age, as runners, I believe we have opportunities to achieve our ‘best days’. These may be by just working harder and smarter (by following my blog for example)  or getting a qualified coach from an awesome running centre (see above) to give you new training ideas. Nutrition is another area I believe we can all probably improve on and I will be making a big effort next year as I give a sub 2:40 marathon time one more tilt in my 50th year on this wonderful planet.  Also as we age I believe we are better equipped to handle the longer distances as marathons and ultra-marathons become more manageable.  Ultra marathons also take away the need for pace and concentrate more on distance, another opportunity to shine as I also believe as we age we have a higher pain threshold. (This may have something to do with bringing up kids (in my case three wonderful Daughters)  and all the challenges this presents, bless ’em ! )

So when it comes to your best days look forward, do not turn around and look behind you, there’s nothing there worth looking at…….

I’ve mentioned before a quote from Brendan Foster below…

As I said in an earlier post I actually turn that quote around as in my experience I got to bed tired and wake up really tired. Maybe that’s why I’m not an international athlete ? This morning was no exception, at 4:50am I was in no mood to run my go-to 10k ‘old faithful’ for the 170th time (thanks Strava https://www.strava.com/activities/776584306 ) My old friend fatigue had come to visit and I could feel the legs were none too impressed as I set off on my morning 10k. As with most morning runs I soon got into the groove and plodded along enjoying the morning ambience and reveling in the sunrise as I cruised through Star Swamp. When I finally finished I had sneaked under 5min/k average for the distance and even raised my VO2 score , so all-in-all a good result.

Walking to work, after a quick coffee stop at my favourite café, I climbed my indicator stairs to get a feel of how my legs were feeling. The stair test is a good test as if you are fatigued you will feel it as you ascend, especially if you go two at a time. This morning I could feel climbing the stairs was a challenge and again the legs were complaining from the start. Fatigue had come calling.

The second week after a marathon you are still in recovery mode so I am not surprised I am feeling fatigued, I would be more worried if I wasn’t as this would mean I could have run faster. (Trust me, I could not have run faster at the World Masters 10 days ago.)  So fatigue in this case is a good thing, it just needs to be managed. By managed I mean as an indicator it is telling me to keep on doing what I’m doing,  which is recovery pace only.  I’ll feel better when I run lunch time (I can’t not run twice a day, that would be silly.) and I actually improve throughout the day. That’s why I turn Brendan Foster’s quote around.

This brings me to the main reason for this post. With fatigue being more prevalent for me at the start of the day I know to make this run the easiest. My lunch time run I know I’ll feel better so can use this one for any harder workouts. Other people feel differently (International athletes apparently?)  and would go harder in the mornings. As with all things running it is a personal thing. I sometimes wonder why I wrote this blog as I am sharing things that work for me but you need to be aware these are my personal findings, as long as you realise that and adjust for your training all is good. I’ve said before most of the topics I discuss are all common sense, I don’t pertain to be a exercise guru, just a runner who loves running and has had some success (at my low level) who also enjoys typing.

As with all things I discuss I have added an article to help or support my ramblings and surprise surprise its my old mate coach Jeff from Runners Connect.

Why Fatigue is a Necessary Part of Training and How to Manage It

Training is like trying to walk a tight rope. You need to balance putting in grueling workouts and mileage with the ability to let your body recover. Favor one aspect too heavily and you’ll either have a poor performance from lack of training or get injured and overtrained from doing too much.

That’s why learning how to manage fatigue, and understanding the role it plays in endurance training, is critical to improving as a runner. In this article, we’re going to outline why a certain amount of fatigue is necessary to improve as a runner, how to strategically implement it, and how to find the right balance.

Why fatigue is necessary

The basis for all training theory is the what we call the workout and recovery process. Running first breaks down your muscle fibers. The harder you run, the more muscle fibers you damage. Your body then works to rebuild these damaged muscle fibers and if the recovery process goes well, these muscle fibers are repaired stronger than before. That’s how you become faster and stronger through training.

But, as you may realize, it’s nearly impossible to fully recover from a workout in 24 hours. It might be possible following a very easy day of running, but any type of speed, tempo or long run is going to require anywhere from 2 to 14 days to fully absorb and recover (here’s a breakdown of what research says about how long it takes to recover from different workout types).

That means, unless you want to only run two or three times per week, training while fatigued is a necessary part of training; especially since we know slow, easy mileage is the best way to build aerobic endurance and is the foundation for running performance. The trick is finding that balance between running enough miles to build you aerobic capacity without overdoing the fatigue.

Herein lies the “art” of training.

However, there is also a way that we can utilize this fatigue to make your training more effective.

How to utilize fatigue to run faster

In training vernacular, coaches use a term called “accumulated fatigue”. Basically, this theory posits that fatigue from one workout accumulates and transfers to the next run so that you’re always starting a workout or a long run a little tired from your previous training.

This is important for longer distance races like the marathon because it’s nearly impossible to run the full distance of the race in daily training. Furthermore, if you were to start every workout fully recovered and fresh, it would be difficult to simulate how your body feels late into a race.

As such, we can strategically implement the theory of accumulated fatigue to better target the specific demands of your race.

For example, during marathon training, one of my favorite methods for introducing accumulated fatigue is to buttress the long run against a shorter, but steady paced run the day before. As an illustration, you would run six miles at marathon pace on the Saturday before your Sunday long run. Because of the harder running on Saturday, you start Sunday’s long run not at zero miles, but rather at six or eight miles, since that is the level of fatigue and glycogen depletion your body is carrying over from the previous run.

You can even apply this theory to 5k training. Using what we know about muscle fibers and the recruitment and fatigue ladder, I often have athletes run a short, explosive hill workout (something like 9 x 60 second hills at 5k pace) two days before a 5k specific workout (12 x 400 at 5k pace with 60 second quick jog rest). The hill session fatigues and depletes the fast twitch muscle fibers so that during the 5k specific work, your intermediary Type IIa muscle fibers (the ones primarily responsible for running at 5k pace) have to handle more work and thus are more specifically targeted.

How to find the right balance

Training would be much easier – and runners much happier – if you could just train hard and fatigued all the time. But, you can’t simply continue to accumulate fatigue and run these types of workouts all the time (although some runners certainly do try). There needs to be a balance.

• First, try to keep the specific accumulated fatigue workouts to once every two weeks and only schedule them during the race-specific portion of your training schedule. This ensures that you don’t overdo it and that you don’t get burnt out long-term.

• Be sure to keep your easy runs slow. One of the most common mistakes runners make is running their easy day mileage too fast. This hinders your ability to recover and doesn’t provide any additional aerobic benefit. Research has shown that the most optimal aerobic pace for an easy run is about 65 percent of 5k pace. For a 20-minute 5k runner (6:25 pace for 5k – 7:20 pace marathoner), this would mean about 8:40 per mile on easy days.

• Finally, don’t be afraid to take a down or rest week every five to six weeks where you reduce mileage by 65 to 75 percent and reduce the intensity of your workouts. These down weeks help you fully recover from and absorb previous weeks and months of training so that fatigue doesn’t build-up too much.

Hopefully, this lesson on fatigue and how you manage it will help you train more intelligently for your upcoming races.

Footnote : Managed a 10k run in Kings Park over some hilly terrain and trails lunch time. Felt a lot better than this morning as expected so will look forward to the alarm tomorrow morning as I’m running with my friend Mark Lee who is a lot quicker than me and more of a short distance specialist.  Only saving grace is we meet at Yelo so the obligatory coffee and muffin will be dangled as reward for the beating he’ll probably give me. On the downside I think it’s my turn to pay…
