Hydration during endurance events is crucial, as it helps maintain performance and prevents dehydration-related issues. Extended physical activity can lead to significant fluid loss through sweat, which affects cardiovascular function and can impair stamina. Proper hydration strategies, including timing fluid intake and electrolyte replenishment, are essential for sustaining energy levels and optimizing endurance. Adequate hydration before and during an event assists in maintaining optimal body temperature and physical performance. Therefore, prioritizing hydration is key to achieving success in endurance sports and preserving overall health.
