Cycling Time Trial Hydration: Aero Position Fluid Strategies
Time trial performance depends on maintaining both wattage and aerodynamics over 20–60 km. Hydration strategy must balance fluid needs (1.0–2.0 L/hr sweat loss at TT intensity) against CdA penalties from drinking. Pre-race hyperhydration, aero bottle placement, and knowing when to skip drinking are key to fast splits.

Heat Training Hydration: Protocols for Plasma Volume Expansion
Heat acclimation training can expand plasma volume by 8–12% in 10–14 days, delivering tangible endurance benefits including lower heart rate, improved thermoregulation, and increased VO2max. The hydration protocols used during and after heat sessions determine whether this adaptation is maximised or blunted.

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.
