Hydration status during endurance events can be monitored by assessing thirst, checking body weight, and evaluating urine color. Athletes should drink fluids regularly, aiming to replace lost fluids according to pre- and post-race weight. Light yellow urine typically indicates adequate hydration. Furthermore, tracking sweat rate can help athletes understand their hydration needs better. Staying proactive about fluid intake during events is essential for maintaining optimal performance and preventing dehydration.
