Beat the Heat: Olympic-Level Strategies for Triathletes to Thrive in Summer
As the sun blazes down, turning training sessions into a battle against the elements, many triathletes find themselves wilting under the intense heat. However, for those who embrace the challenge, the scorching summer can be transformed into a formidable ally. With global temperatures on the rise, mastering heat adaptation is becoming a crucial skill for any triathlete aiming for peak performance.
Dr. Trent Stellingwerff, a leading sports scientist and coach at the Canadian Sport Institute, has dedicated years to perfecting heat adaptation strategies for Canada's top athletes. His insights are invaluable not just for the elite but for any triathlete looking to conquer their summer races or use the heat as a springboard for fall events.
How Heat Impacts Triathlon Performance
Each segment of a triathlon reacts differently to heat, posing unique challenges:
- Swimming: While cooler waters can mask early heat stress, wetsuit-legal swims in warmer temperatures might increase your core temperature right from the start.
- Cycling: The sun's rays and the heat from the asphalt combine with your body heat, escalating thermal stress, especially if you push too hard.
- Running: Often the final and most brutal leg, running in the heat can severely impair performance, with every degree above optimal reducing your output by up to 3%.
The performance decline in heat isn’t gradual. It's more like a cliff. Once you hit your heat threshold, your performance can plummet as your body prioritizes cooling over running.

The Science of Adapting to Heat
Heat adaptation involves acclimating your body to thermal stress through specific, repeated exposure. This process triggers several physiological changes that enhance your performance in hot conditions:
- Increased plasma volume: Enhances cardiovascular efficiency.
- Earlier and more intense sweating: Helps cool the body quicker.
- Lower core temperature and heart rate: During exercise.
- Improved thermal comfort: Makes heat less daunting.
Heat acclimation can improve performance in hot weather by 6-8%—a significant margin that can be the difference between triumph and defeat.

Practical Heat Training Techniques
Depending on your resources, there are several ways to train for heat:
- For the budget-conscious: Overdress during regular workouts or take hot baths post-training to simulate heat stress.
- For those with access to more resources: Utilize heat chambers or engage in thermal training camps in hot climates.
A typical 14-day heat adaptation protocol might look like this:
- Week 1 (Introduction): Start with short sessions of overdressed training or brief post-workout heat exposures.
- Week 2 (Optimization): Gradually increase the intensity and duration of heat exposure.
Consistency in exposure is crucial. Regular, moderate heat training is more effective than sporadic, intense sessions.

Hydration and Nutrition in the Heat
Proper hydration and nutrition are critical, especially in hot conditions:
- Hydrate aggressively before events: Aiming for 5-7 ml per kg of body weight.
- Use cooling strategies: Like ice slurry ingestion or cooling vests during warm-ups.
- Adjust your race nutrition: To account for increased carbohydrate consumption and electrolyte loss in the heat.
Smart Racing in Extreme Heat
Even with optimal preparation, you'll need to tweak your racing strategy:
- Start slower: Than usual to manage your heat load from the outset.
- Use every cooling opportunity: From ice-filled bandanas at transition areas to grabbing extra water at aid stations.
- Focus on perceived exertion: Rather than pace, as the heat will skew your usual speed metrics.
