What is the central question of this study? The aim was to identify the factors predicting the body core temperature of athletes at the end of a 10 km self‐paced run in a hot environment. What is the main finding and its importance? Hyperthermia in athletes subjected to self‐paced running depends on several factors, highlighting the integrated control of core temperature during exercise under environmental heat stress. Five of the seven variables that significantly predicted core temperature are not invasive and, therefore, practical for use outside the laboratory environment: heart rate, sweat rate, wet‐bulb globe temperature, running speed and maximal oxygen consumption.
