Race Day Cooling Strategies: Precooling, Ice Vests, and Cold Water
Internal precooling drops core temperature by 0.3-0.5 degrees C before a hot-weather race. Ice vests extend time to exhaustion by 7-16%. A structured cooling protocol from 30 minutes pre-race through the finish line can be the difference between a strong performance and an early DNF.

Training in Heat and Humidity: Why Humidity Changes Everything About Hydration
High humidity prevents sweat evaporation — the body's primary cooling system — causing heat to accumulate despite continued sweating. WBGT thresholds, humidity-adjusted fluid targets, and sodium replacement protocols for summer training and tropical race preparation.
