Before we continue with my series on How To Qualify For The Boston Marathon, I would like to mention my first Coach in Ultramarathon before I applied at the CTS Coaching Service. When I started running ultra trail events, Karl Meltzer had been one of my Idols as he would win as Champion, at least, one 100-mile trail ultra race per year. Now, he is considered as the Winningest 100-Mile Ultra Runner In The World. You can check it out in his website here.
From 2014-2016, I have been coached by Karl Meltzer and I subscribed to his Training Plan Only which cost me $ 300.00 every 3 months. It was a very simple arrangement, he asked me for my personal data and then sent me a separate e-mail message for the list and illustrations of strength exercises that I can do as part of my training. Later, he would send me my 3-month training schedule in miles with one day of the week as Rest Day. No specific description of running workout was stated in the number of miles that I have to run daily. However, my weekly mileage would be ranging from 50-55 miles per week as my Average Mileage. When a race is about one month away, he would increase my weekly mileage to 60-65 miles per week. I can still remember that most of my runs were then progressive runs on the trails. All my communications with him were through e-mails. No nutrition advise and no feedback system in my daily workout was discussed. It was purely running on trails with no elevation requirements. He was not very technical and specific in my training program. However, I am not sure if his more advanced and more expensive training program would include nutrition and other feedback system. In fairness to the Coaching/Training I got from him, I became a stronger and faster trail runner.
In my interview with the Senior Coach of CTS before I started being their athlete, I told him that I was a former “client” of Karl Meltzer’s Coaching for two years and maybe, such information gave him the assurance that I had already the experience of being coached by an elite ultrarunner and he would gauged me on my present condition as an ultrarunner. By the way, a runner being coached by Karl Meltzer is called a “client” while CTS call their subscribed runners as “CTS Athlete”. I think there is a big difference there in terms of impression/opinion on how to describe the “coach to student relationship” in each Coaching Service. Personally, I would prefer being called a CTS Athlete as it impresses other people that you are a member and integral part of their Coaching Service.
When Hoka One One Shoes came up with their Shoe Model with the monicker name “Speedgoat” of Karl Meltzer, I wrote a Shoe Review of the said shoes as I was one of the few who introduced it in the local trail running circuit. That is how I idolize and respect this guy. Actually, if not for the Covid-19 situation, I would have the new Speedgoat right now in my possession and ready for another Shoe Review.
I will continue with my series, How To Qualify For Boston Marathon, tomorrow. Thanks for reading.
I am not trying to force-feed you with the training that I did with CTS as I want to share my story from the time that they accepted my application as one of their CTS athletes. I was just lucky that I was able to contact Jason Koop when he was advertising the publication of his book on Ultrarunning in May 2017 and asked him if CTS accepts a 65-year old runner.
After I applied on line on their Website, I was asked to answer (on line) a questionnaire, asking my personal data, experience and number of years of training, and if I had a recurring running injury. After a few days, one of their Senior Coaches contacted me through e-mail and gave me instructions on how to set up my Premium Training Peaks Platform by giving me my Signing-In data. I think it costs me $70.00 as full time payment for my subscription with Premium Training Peaks. Two of my GPS Watches (SUUNTO Ambit 3 Peak and Garmin Forerunner) were linked to the said Training Site Platform. Everything (data) that my Coach need to knowabout my daily workout are uploaded to the Training Peaks and you can not fake your effort on those data. The Senior Coach had briefed me about the terms being used on the description of each workout and the specific data that are incorporated in the workout. Above all, my workouts were given to me in the number of hours and minutes and not by the number of miles or kilometers that I have to run in each day. My Coach asked me what is my preferred REST Day for the week and I said, I would like it on Mondays.
My Coach would send me my training workout for two weeks and each day I should give my feedback how my body felt in terms of effort from EASY to Very HARD, the rank measurement is from 1 to 10 with Rank 1 as Very Easy and 10 as Very Hard. It is a also a “must” that you send a short message as how you felt during and after the workout. Your feedback description will be gauged in terms of your fitness condition, fatigue, and motivation.However, your feedback will be matched with numerical data captured from your GPS Watch and as seen on Training Peaks. At the end of the week, you can easily see your totals in terms of the total number of hours and the total of miles/kilometers you covered from those hours.On those first days as CTS athlete, I would review the Book on Ultrarunning by Jason Koop making sure to know the description and details of each workout I was given to do.
It is worth mentioning that the Coach would prescribe in each daily workout the following description: (1) the number of hours and minutes of your total workout; (2) each workout is described from its warm-up period (in minutes), main workout (in hours and minutes, depending how long is the period), cool-down period (in Hours/minutes); and (3) the type of terrain where the Coach would suggest you to run, whether it is flat road, trail, or in a course with hilly or steep elevation. The Coach would suggest also your “Total Score Stress” (TSS) where Training Peak would refer it as Running Total Training Stress (rTSS). Depending on what type of workout, the Coach will designate an rTSS score for a specific workout (Easy Run, Endurance Run, Tempo Run, Hill Repeats or Interval). The higher the score, the more the stressful the run. Thus, your workout will be quantified in terms of training stress for a specific running workout. Once I upload my workout from my GPS watch, my rTSS for the workout will be immediately compared with the suggested rTSS from my Coach. Most of the time, my workout rTSS would not surpass or equal my Coach rTSS. But in my feedback, I felt that I am wasted as a result of the workout. Anyway, whether I can equal or not on the required rTTS, my personal observation was that I was running stronger every week.
For the first two weeks of training workout, I was given a mix of Endurance Runs, Tempo Runs, and Recovery Runs from the duration of One Hour & Thirty Minutes to Two Hours. In the succeeding weeks, I was introduced with Hill Repeats. After three weeks, I was asked to conduct a “20-minute field test”. It is done by having a 15-minute warm-up run first and then I did my fastest 20-minute run along a flat paved road, and then had a cool-down for 30 minutes. The result of my “20-minute field test” determined my Average Pace for the Tempo Run. The Average Pace would be my target time whenever I do my Tempo Runs. Most of the succeeding weeks will be devoted to Tempo Runs and Hill Repeats! I was surprised that my Tempo Run’s Average Pace would be faster than my usual Tempo Pace. Before, I could not breach less than 9:00 minutes per mile pace with too much fatigue and pain to my legs and body after each workout. But after3 weeks of CTS training, I was able to breach the 9:00-minute barrier and with more regular “test runs”, I was able to record a 8:09 minute per mile paceand then lowered it to 7:30-minute pace. With my age and not-so-perfect running form and short legs, I could not believe how fast I could make those leg turn-overs whenever I do my tempo runs on a flat paved road. Since I was preparing for ultra trail runs in the future, I did not have a chance to run on the oval track. I guess, I could run faster if those “20-minute field test” runs were done on an oval track.
One month before the Javelina Jundred 100-Mile Endurance Race, I was given more time for my Endurance Runs on trails in my Playground and they would last from 4 hours to 6 hours. CTS would not allow their athletes to run more than 6 hours in their Endurance Runs for the basic reason that the runner could not recover in a span of one to two days. CTS wants their athletes to be fresh and feeling stronger after a day of recovery. The training concept on those four months was clear to me as it followed the training concept and principles written in the book of Jason Koop—-assessment of my body on the 1st two weeks, followed by fast runs through tempo runs and hill repeats, and then Endurance Runs on the last weeks leading to the target race.
Bottomline, with those 4 months leading to JJ100, I was not injured, my body was always fresh and recovered on Tuesdays, and felt becoming stronger during my Tuesday runs.
In the next succeeding posts, we will go to the details of my daily workouts.
I just want to review the things that I do when I am running in my training and races. Most of these things are known already by runners but sometimes they forget when fatigue and pain come into play at the middle of the run. I usually do these “tricks” to focus or bring back my mind into running as we tend to be distracted by some factors, whether they are external or internal to one’s body. So, these are the tricks that I do:
1. Strides: This trick is described as quick increase in pace or speed for a short distance or time followed with an interval of slow pace. Most of the time, the time elapsed during a particular stride should be the same period with the slow pace. I am usually asked by my Coach to do some “strides” during or at the end of my Warm-Ups and during my Cool Down. However, at the middle of my Races and training workouts, I usually apply these “strides”. Usually, I adopt the “30-second” duration of “strides” which I estimate 30 counts whenever my right of left foot hit the ground.
2. “30-30”-Second Run: Actually, this is the same with “strides” and it was popularized by Kilian Jornet’s technique in running trail events. The first 30 seconds consist fast run and the next 30-seconds in easy run. This cycle is repeated throughout the run or race. Just the same with the strides, I usually count my right or left feet landing/hitting the ground from count one to thirty on fast pace and then shift to an easy pace with the same number of counts. If one can do this consistently, a runner can run as far as he can. This is what I adopt in my running, whether I am on the trail or road. This is my favorite drill during my endurance trail runs and during my road runs.
3. “30-20-10”-Second Run: This drill run is done by doing first a 30-second easy run, then followed with a faster 20-second run, and finish with a 10-second “sprint” to complete the cycle. You can repeat this cycle drill as long as you want. I usually do this drill in 4-5 cycles in the middle of my workout. As you progress, a runner can increase the number of cycles at least one cycle per week until comfortable to do 8 cycles in a single running workout.
4. “Fartlek” Run: Simply look for an object far in front of your running path and then “sprint” towards the said object. Take an easy and relaxed run after the sprint and then repeat the sprint if you feel you have already rested/recovered. Repeat the process as long as you want. You can walk as your rest/recovery in between sprints. You can start with 4 repetitions in a single workout and then steady increasing the number of repetitions within the middle part of your running workout. This workout is done once or twice a week.
5. Counting Steps or Strides: In the middle of my runs, I usually count my strides, whether they are easy or fast, from one to 90. In my estimate, 90 strides is equivalent to one minute which in turn would estimate me running a stride rate of 180 steps per minute. I usually do this drill when I would force myself to jog or to have an easy run instead of walking on the downhills or flat roads.
Most of these tricks were taken from the experiences shared by other runners. Some were taken from running books and articles from running magazines with the proper studies made by Sports scientists and sports physiologists. You can adopt one trick or you can combine all of these tricks in a single workout. It is up for the runner to choose which one is fitted for their prevailing running condition and purpose or objective while running.
I started to get the guidance of a Professional Coaching Service in my ultrarunning/running in the middle of June 2017. Actually, it was my second experience to get the assistance of a Coaching Service abroad. The first one was with Karl Meltzer and it lasted for one year although I was the very basis Coaching Program that I have enrolled in. I became a very strong ultra trail runner in a short period of time and his Coaching/Training Schedule made me finished 3 successive finishes in the Clark Miyamit 50-Mile Ultra Trail; 2 Finishes in the Translantau 100K; and Tarawera 100K finish in New Zealand. My two attempts in the San Diego 100-Mile Endurance for two successive years did not go as planned because of GI issues related to excessive Heat Exhaustion in a desert environment and Nutrition problems. On hindsight, it maybe due also to overtraining and lesser appreciation of rest and recovery in between training blocks or in between race events.
When Jason Koop, author of Training Essentials Of Ultrarunning, published his book, we started to become friends on Facebook and that I would be one of the first to purchase it. And even went to the extent of recommending it to my FB friends after getting the full appreciation of his scientific approach to ultrarunning training. It took me sometime to read the book and started to apply its concepts in my daily training. Not until an advertisement popped out on Internet that CTS was offering One Dollar First Month Fee for their Coaching Service. I immediately sent an inquiry to Jason Koop through Direct Message and he replied to me instantly with a positive note. I told him that I am a 65-year old and I need to be a better mountain trail ultrarunner.
After a week of processing, I got a designated Coach and Premium Training Peaks platform where I can upload the data from my GPS Watch and at the same time, where I could see my Training Schedule. John Fitzgerald is my Coach and he would give me feedback almost everyday and I could arrange a scheduled phone call or simply send him a SMS regularly if I need some inquiries or inform him about my feeling/s during and after workout. He would know my races and adjust my training based from the information available from the event.
After one year being an athlete of CTS even if I failed in my scheduled Ultra Races last year and this early part of 2018, I admit that CTS and Coach John Fitzgerald were the primary factors/reasons why I was able to qualify for the 2019 Boston Marathon and most of all, not being “burned out” in every training block and in between my racing events.
On hindsight, I think I have over estimated myself in choosing very hard races in Europe & USA which are part of the Ultra Trail World Tour (UTWT) series. I should have chosen those shorter ultra versions of these races which could had served as my initial exposure or recon runs in these very challenging races. However, at this time, I knew that I am ready to go back in these places/races and more confident to finish these races with the support of CTS.
For an old and passionate runner like me, CTS will be my partner and guide to tackle more challenging ultra mountain trail races in the future.

Being a CTS athlete, I regularly receive in my e-mail articles written by CTS Coaches of articles related to the Sports of Ultrarunning and other Endurance Sports. The following article is very timely for those athletes and runners who will joining ultra marathon events in the months of July up to the later part of October in the United States as most of these events happen during extreme heat temperatures.Personally, this had been my problem through the years on why I failed to finish 100-mile trail races in California, Utah and Nevada in the past years. However, with my Support Crew and Pacing experience in last month’s Badwater 135-Mile Ultramarathon, I was able to solve my problem on my hydration and heat prevention. Through the help of my CTS Coach John Fitzgerald, I was able to correct my electrolyte imbalance whenever I run in an environment that is too hot during my training in my Playground in the Philippines. For the past three months, I had been weighing my body before and after my runs in order to determine my body sweat loss within a period of time of running. As a result, I would determine how much liters of water and electrolytes I would carry depending on how many hours I would be out for my run, whether in the early morning or late in the afternoon.
As I continue to write and post my 2018 Badwater 135-Mile Ultramarathon, I will mention something on the later part of my blog on how I was able to manage the extreme heat during the time that I paced Tess Leono for almost 32 miles (50 kilometers) under the heat of the sun.
Without much further ado, I am now reposting this article and I hope that those who are planning to do ultramarathon races in hot environment will learn a lot and be able to apply the preventive measures stated in this article. Let this be a reference to all ultra runners out there.
Heat Illness and Endurance Athletes: The Science of Staying Safe When It Gets Hot
By Corrine Malcolm CTS Coach and Exercise Physiologist
Human beings are inherently inefficient. Only a fraction of the work athletes do ends up propelling them down the road, up the mountain or through the water. The rest just of that work generates heat, which has to go somewhere. Normally, the body is reasonably good at dissipating heat, until the environment is also hot and/or humid. Heat illnesses develop when you can’t adequately dissipate heat to the environment, and involves an incredibly complex relationship between your thermal physiology (all that heat you are producing), environmental heat strain, and your clothing (2). Many experienced endurance athletes are well versed in hydration and cooling strategies, but as a community it is crucial for all athletes to understand the signs and symptoms of heat illness, how to prevent it, and how to help athletes suffering from it.
Heat illness doesn’t care how much you know about hydration and cooling. Despite all the right preparations, even experts and experienced athletes can end up with heat illness when things go wrong during training or competition.
There are two main types of heat illness: classic and exertional. Classic heat illness is directly related to the environment and how the environment is effecting one’s ability to dissipate heat. These factors include high temperature and humidity, strong direct sun exposure, and still air. Exertional heat illness on the other hand is primarily caused by your own heat production, which is why exertional heat illness can occur in all types of weather (3). It should be noted that the treatment and identification does not change between classic and exertional heat illness, but illustrates the fact athletes should be aware of the signs of heat illness even in cooler and less humid environments.
UNDERSTANDING YOUR ENVIRONMENTAL RISK BEFORE A RUN, RIDE, OR RACE CAN BE CRITICAL FOR SUCCESS AND YOUR HEALTH (4).
Body’s Response to Heat Exposure
Although 98.6 F (37 C) is generally accepted norm for human body temperature, it is normal for core temperature to fluctuate within a small range of 97-99 F (36.1-37.2 C). When your body increases much above or below this “set” temperature you can experience hyperthermia or hypothermia as your body tries valiantly to bring your body back to homeostasis. When you get too hot your one of the best way your body can cool itself down is to shift more blood flow to the capillaries that lie immediately underneath your skin. What this allows your body to offload some of the heat into the environment and in turn send cooled blood back deep into your body. The second way your body combats the likely rise in core body temperature is by increasing your sweat rate. This allows you to utilize evaporative cooling, which cools the body by creating a temperature gradient as sweat (or other water) evaporates from your skin surface into the air. The neat thing about the increase in your sweat rate per hour during the heat is that your sweat becomes more dilute than usual which makes it even easier for your sweat to evaporate from your skin into the air.
Additionally, there are three environmental mechanisms that can both prevent your core body temperature from increasing and also increase your core body temperature. Those mechanisms are radiation, convection, and conduction. All three rely on temperature gradients where the heat goes from the warmer environment to the cooler environment. In an ideal world that means your body is the hot environment and you are able to dissipate heat into the surrounding environment (5). While you exercise and race your body relies on these thermoregulatory adjustments because during exercise you produce 15-20 times more heat than you do at rest. Without these crucial adjustments, either physiological, environmental, or behavioral changes, your core body temperature will rise 1.8 F (1C) for every 5 minutes of exercise (3).
Levels of Heat Illness
Heat-related illnesses start out mildly uncomfortable and progress all the way to life threatening. The conditions are, from least serious to most serious: heat edema, heat rash, heat syncope, heat cramps, heat exhaustion, and heat stroke (3,4).
Heat Edema and Heat Rash
Heat edema and heat rash are both the mildest forms of heat illness you might experience. Heat edema can occur as your body tries to dissipate heat by vasodilation and a shift of blood flow to your skin. This most commonly happens in the lower extremities as fluid creates inflammation in your feet and ankles. Heat rash (also called prickly heat or miliaria rubra) is a pinpoint red rash that forms on the skin that was covered by clothing. This generally happens in areas that have a higher concentration of heat glands, like your trunk and groin, and is caused by the increase in sweat saturating the clothing and your skin surface clogging sweat ducts.
Heat syncope, or fainting caused by heat, may happen during heat exposure because blood is being shunted to your skin and extremities. Rapid changes in body position (commonly sitting to standing, or bending over and standing back up) can lead to a temporary change in blood pressure that causes a person to faint. Most athletes recover quickly once laid flat, which allows blood flow to normalize. That being said, falling due to a rapid loss of consciousness could lead to a concussion, and an athlete who faints due to heat should be evaluated before being allowed to continue training or competing.
Heat cramps or muscle spasms have been notoriously linked with dehydration and electrolyte imbalances over the year. However, we now know exercise associated muscle cramps are more commonly associated with a wider range of variables such as fatigue and muscular imbalances. Although harmful to performance, exercise associated muscle cramps are generally harmless to your health and most commonly occur on one side of your body (i.e. your left quad or your right calf). If you are experiencing bilateral, or both sides, cramping or full body cramping, this is often linked to a more serious condition such as extreme dehydration or hyponatremia (depleted electrolytes from excessive water consumption) and should be immediately addressed by your physician or the medical team at your event.
As we move up the scale in severity we come to heat exhaustion. Heat exhaustion should be taken seriously and treated quickly, as it can advance to more serious and potentially life-threatening conditions like heat stroke. Heat exhaustion generally presents with fatigue, dizziness, heavy sweating, nausea, vomiting, headache, fainting, weakness, and cold clammy skin. A person with exhaustion typically still has normal cognitive and neurological function. They should be able to answer questions about their condition, where they are, who they are, etc.
Heat stroke is characterized by a core body temperature greater than 104 F and altered central nervous system function, including irritability, confusion, combativeness, or even worse, loss of consciousness. Hot and dry skin is a sign of heat stroke, but it is important to realize a person can be sweating and still have heat stroke. Altered central nervous system function is the hallmark difference between heat exhaustion and heat stroke, but when in doubt, treat the situation as if the athlete has heat stroke. Athletes showing signs of heat stroke need to be treated by medical professionals as soon as possible. It should be stressed that heat stroke is incredibly serious and can lead to death if not treated quickly.
THE CONTINUUM OF HEAT ILLNESS (3).
Risk factors for developing heat illness
The most recent estimate is that heat related illnesses cause 695 deaths per year in the United States, but they are the 3rd highest cause of death amongst athletes. There are two main categories of risk factors: environmental (external) factors and physiological (internal) factors.
Environmental factors include how hard you are working, clothing choices, insufficient shade during activity, lack of access to water, ambient air temperature, and humidity. Internal factors include age (people under the age of 15 or over the age of 65 are more susceptible to heat illness), recent alcohol consumption, acute or chronic dehydration, history of heat-related illness, medication or supplement interactions, recent illness that included a fever, recent head injury, sunburn, skin conditions (eczema or psoriasis), or insufficient heat acclimation (3).
Treatment of Heat Illness
As with many medical emergencies, time is an extremely important factor in treatment of heat-related illnesses. The goal is to get core body temperature down to an acceptable level (below 38C or 100.4 F) as quickly as possible. It’s important to note that although fevers generally present at similar temperatures to what we call hyperthermia (temperatures above 100.9 F) the underlying mechanism is different. In general, our thermal max is a narrow range from 106.8 -107.6 F. Sustained core temperature at this level for anywhere from 45 minutes to 8 hours can be lethal, and one of the factors for predicting the outcome for a person with heat stroke is how long they are hyperthermic. Body temperature of 106.8 – 107.6 F may seem awfully high, but when you are exerting yourself in hot conditions, it is not uncommon for body temperature to reach 102-103 F for short periods of time. Adverse conditions, either internal or external, can cause core body temperature to stay elevated or rise to higher, more dangerous, levels.
The key takeaway from research institutes, such as the Korey Stringer Institute, that focus on heat-related illnesses is to cool the athlete down as quickly as possible to protect the athlete’s brain and vital organs. To do that, the critical first step is to recognize you or another athlete is in trouble. This step is often missed, which allows heat illness to progress to dangerous levels. Get out of direct sunlight and into a shaded, cooler environment. Finally, use whatever you have to cool off. This can include dousing with cold water from a hose or shower, wrapping in cold towels, applying ice packs or immersion in an ice bath, and having them ingest cold fluids. Athletes experiencing heat stroke need medical care immediately, with the goal of lowering body temperature to below 104 F within 30 minutes.
Preventing Heat Illness
The best ways for athletes to avoid heat-related illness are to heat acclimatize before training hard or racing in a hot environment, monitor and manage your hydration needs, and utilize cooling techniques to help manage your core body temperature. Doing these three things well will reduce the physiological strain of training and racing in the heat and optimize performance.
The most important of these three is heat acclimatization because it not only improves thermal comfort, or your psychological tolerance to the heat, but also it improves your physiological thermal tolerance, which is your body’s ability to tolerate heat exposure for an extended period of time. The physiological benefits of heat acclimatization include increased skin blood flow and increased sweat rate, both of which help to dissipate heat quickly and efficiently. During heat acclimation you also have an increase in your blood plasma volume, which allows you to better sustain your blood pressure and work capacity (1). These adaptations take roughly 7-14 days to fully manifest. Because of this, it is important to monitor your level of exertion as your body makes these adaptations. During this time you will naturally have a change in threshold pace, power output, and both maximal and submaximal heart rate. Don’t force it.
Dehydration is one of the key precursors to developing a heat-related illness. Although dehydration generally occurs from an inadequate intake of fluids, it can be made worse by an excessive amount of fluid loss through sweating, putting you in a state of hypohydration (Howe et al). Regardless of whether you’re putting too little in the tank or losing to much from sweating, from an athletic standpoint it has been shown that your heart rate will rise 3-5 beats/min for every 1% of bodyweight loss due to dehydration (Coris et al). When dehydration occurs your blood plasma volume shrinks, which not only effects your heart’s ability to do its job, but also decreases blood flow to the skin and sweat rate. As a result, performance declines and the chances of developing heat illness increase.
What this means is that you should monitor not only your during-activity hydration but also your pre-exercise and post-exercise hydration when temperatures begin to rise. It is recommended that you start your exercise or race euhydrated, which just means starting at a normal level of hydration and not getting to the start line dehydrated or hyperhydrated. Adjusting your day-to-day hydration status takes some time, and guzzling fluid isn’t helpful. Rather, try the WUT method and make appropriate adjustments to daily fluid intake.
When it comes to hydration during exercise the idea is to minimize losses in total body water mass. During strenuous exercise in the heat, sweat rates can reach 1.5 liters per hour, and sometimes higher. General recommendations are to consume 16 – 24 ounces of fluid an hour, but endurance athletes in hot environments often need to consume 2-3 times that much. You can figure out your approximate sweat rate by weighing yourself pre- and post-workout. When it comes to post race or activity hydration the old staple was to try and replace 150% of body mass losses during the first hour of your exercise stopping (6). For many athletes this simply wasn’t practical and caused some GI discomfort, and because of this the most realistic guideline is to try and replace 100-120% of body mass lost in the first hour after you stop exercising (1) and continue consuming fluids in the hours after that. CTS has long recommended athletes aim to consume 150% of fluid losses within 4 hours after exercise.
The final components to avoiding heat-related illnesses are the little things you can do to work with your environment and not set yourself up for failure. You can choose to wear light colored and loose fitting clothes. Additionally, you can utilize two different methods of managing heat exposure by either continuous cooling methods or pre-cooling techniques. Continuous cooling methods utilize both external and internal cooling methods. Some external cooling methods include the application of iced/cooled down clothing, towels, water immersion or dousing, or packing ice onto athlete via ice bandanas, ice socks, or into clothing and hydration vests. Internal cooling methods generally rely on the ingestion of cold fluids or ice slurries to try to maintain a lower core body temperature. When it comes to endurance activity in particular, pre-cooling methods have been shown to be effective in both improving performance and delaying the inevitable rise in the core body temperature. What this means is that an athlete getting ready to compete in a warm environment can benefit from starting their event with a lower core body temperature. This can be accomplished by ingesting cold ice slurries, or now the use of a commercial ice vest (or more simply cold iced down towels around your trunk and shoulders) during your warmup. It’s been shown that these crucial minutes of cooling down before you hit the start line or the start button on your watch can prolong your body’s ability to maintain a lower core body temperature (1).
When it comes to exercising and racing in the heat, prepare yourself for the demands of the environment, manage your fluids, and utilize physical methods of cooling yourself off. Taking a moment to cool off now might slow you down temporarily but cannot only save your race or workout in the long run, but also your life.
