⭐️ Training Tip
Training in Heat: A Challenge for Runners
Summer is approaching, and with it comes a new challenge for runners and endurance athletes. Training in warm temperatures can make even familiar workouts feel significantly more demanding. Heat places additional stress on the body by increasing fatigue, raising the risk of dehydration, and forcing the cardiovascular system to work harder to maintain the same level of performance.
