Ultra-Running Hyperhydration: Fluid Strategies Beyond 50 Miles

Hydration demands in ultra-running beyond 50 miles diverge sharply from standard marathon protocols. Sodium losses of 900–1800 mg/hr, the constant threat of hyponatremia, and the need for real-time body weight checkpoints require a distance-specific fluid strategy that adapts as the race unfolds.
