Heat management is a performance skill, not a survival strategy. When it comes to racing in the heat, most triathletes think about heat mainly in terms of “don’t overheat,” while the best hot-weather racers think about the strategies to reducing thermal strain so they can keep moving forward late in the race. Most importantly, cooling and hydration are not separate topics. They work together to maintain plasma volume, sweat rate, and sustainable pacing. Heat changes the tactics of triathlon racing. As core temperature rises, the body diverts more blood toward the skin for cooling. Sweat losses increase, plasma volume drops, heart rate climbs, and perceived effort rises, even at the same pace or power output. The athletes who perform best in hot conditions are usually not the toughest. They are the ones who manage heat load most effectively. After participating in a lot of hot weather races, here are my personal top tips for managing the heat in order of priority. 1. Th...
