Operating and racing within the warmth isn’t simple. Whether or not you’re operating in a dry or humid local weather, your physique temperature runs greater than regular, you sweat extra, work tougher and run slower in sizzling climate. It’s not solely a bodily burden, but additionally a psychological one, realizing that you simply might need skilled for a number of months for a sure tempo solely to have your aim time thrown out the window for a extra life like pacing technique acceptable to the situations.
Whether or not you’re planning to run in a sizzling local weather or when you have unseasonably heat situations to greet you on race day, there are nonetheless loads of steps you’ll be able to take to maximise your efficiency.
Exchange Misplaced Fluids
In sizzling climate, your physique self-regulates its core temperature by way of a wide range of means. Warmth is moved from muscle mass and launched by way of the pores and skin by convection. Warmth additionally leaves the physique in water vapor as a runner exhales and is dispersed through sweat, a course of that cools the pores and skin and releases warmth throughout evaporation.
However every of these processes works higher whenever you’re optimally hydrated. The fluids you ingest earlier than and through a race—each within the type of a carbohydrate/electrolyte beverage and water—act as conductants that assist transport warmth. The extra fluid or water you might have in your physique, the extra warmth you’ll be able to take away. When you get dehydrated—and thus have much less fluid in your physique—you restrict the physique’s capacity to take away warmth and thus restrict your efficiency.
The important thing to sustaining efficiency in sizzling situations is sufficiently changing the fluids and electrolytes you lose when you’re operating. Though there are really helpful tips for shopper liquids throughout a run or race—roughly 4-6 oz. of carbohydrate/electrolyte beverage each 20 minutes or so—the quantity of fluid wanted varies vastly amongst runners.
Understanding your sweat charge is a method of estimating how a lot fluid you’re dropping at race tempo underneath these temperature situations. If in case you have a excessive sweat charge, you may want to interchange electrolytes extra typically than you want to absorb carbohydrates. Working towards your fluid alternative technique forward of time is essential to maximizing efficiency in heat and sizzling situations, particularly as a result of the physique can extra shortly take up electrolytes if they’re consumed with out carbohydrates.

Begin Hydrating Early
The method of changing into optimally hydrated earlier than a race doesn’t occur in a single day. It truly wants to start out about three days earlier than the occasion. Within the tapering part of your coaching, your physique will retailer extra water and electrolytes, however you continue to must drink fluids with electrolytes and never simply water. Within the days earlier than a race, you’ll be able to drink water with meals as a result of there can be loads of electrolytes in your meals. Nevertheless, outdoors of your mealtime, hydrate with electrolyte drinks so you’ll be able to retain fluid. Additionally, when you’re feeling thirsty or your urine has a reasonable to sturdy yellow colour at any level throughout the days earlier than your race, you’re too dehydrated.
If in case you have a reasonable to very excessive sweat charge, you’ll be able to profit from taking in additional sodium a day earlier than the race. The elevated sodium ranges within the blood immediate your mind to drink extra fluid to steadiness out the sodium ranges. Proceed together with your regular pre-race vitamin routine, and add 3,500-5,000mg of sodium 18-24 hours earlier than competitors to your food plan by periodically taking salt capsules or sodium-packed snacks the day earlier than the race. With the elevated sodium stage in your blood, your mind will immediate you to drink typically earlier than and throughout the race, and assist preserve your electrolyte ranges excessive throughout competitors.
Eat A Cool Breakfast
You’ll be able to preserve your core physique temperature as little as potential by consuming a cool breakfast with meals that can produce a low thermogenic impact. Some folks prefer to eat a plain bagel with peanut butter on it, and whereas that’s wonderful, it’s going to be a little bit tougher to digest—and due to this fact have the next thermogenic impression—due to its fats content material. Ingesting a chilly smoothie or consuming chilled low-residue fruit (grapes, cantaloupe, plums, apricots, melon, peaches, watermelon, applesauce) will assist preserve your core temperature low. Consuming a chunk of white toast with jam on it’s OK, however keep away from uncooked and dried fruits, raisins and berries and prune juice.
Scale back Your Warmup
If heat temperatures prevail earlier than your race, do as little as potential earlier than you get to the beginning line, together with a really restricted warmup session. At that time, it’s actually extra about simply activating your muscle mass, so that you don’t essentially must run in any respect. Usually, I’ve runners do some simple sports activities band stretching simply to remind their muscle mass that they’re on the point of transfer. When you let the race heat you up, you’ll be able to ease into your race paces. You must reduce the period of time you’re out within the warmth and within the solar previous to the beginning of the race.

Begin Slower And Alter Your Objectives
For warm races, it’s essential to readjust your race plans by beginning slower than what you had deliberate and setting your authentic time objectives apart. You’re sure to run slower in sizzling situations, however that doesn’t imply you’ll be able to’t run laborious and switch in a aggressive effort. I sometimes inform runners so as to add 20 seconds to the per-mile tempo they had been planning to run as a secure estimate that can give them the very best likelihood of ending, in addition to competing effectively within the second half of the race. The runners who insist on going out quick on their goal tempo are the runners who wind up stalling out.
Decrease Your Core Temperature
Most individuals don’t have entry to an ice vest (like Deena Kastor did earlier than the beginning of the 2004 Olympic marathon), however you will get a whole lot of profit by maintaining luggage of crushed ice in your physique earlier than a race. Hold the ice round your waist or just lie or sit on a bag of ice will simulate the consequences of an ice vest. Holding one thing chilly in your fingers may also help decrease your temperature a little bit bit (see sidebar), however it could actually additionally inform your mind you might be comfortably cool, ready and able to race at a excessive stage.
Drink Early And Usually
As soon as the race begins, drink fluids at each support station, however don’t make the error of ingesting solely water. You’ll wish to absorb 200mg of sodium and a few potassium with each 8-12 oz. of fluid throughout a race. So long as you’re taking in some form of electrolyte drink, you’ll keep away from the harmful state of affairs of hyponatremia. Drink at each support station and even slowing right down to drink two cups of fluid, one with electrolyte drink and one with water, or possibly two cups of electrolyte drink. You may also profit by carrying a water bottle from the beginning of the race with an electrolyte drink in it or a dissolvable electrolyte tab like Nuun.
