The Athlete's Guide to Hydrating in the Heat

Training in Warm Conditions

Training in warm conditions places greater demands on the body. Heart rate rises. Sweat increases. Fluid losses accelerate.

Summer training is physiologically distinct from cooler-season training. Your cardiovascular system works harder to simultaneously supply working muscles and support normal thermoregulation. The minerals lost through sweat — potassium, magnesium, and others — need to be replaced as a consistent part of any sensible training routine.

Hydration Around Activity

Athletes often think about hydration in three phases: before training, during training, and after training. Starting exercise with adequate fluid and electrolyte intake helps support normal muscle function throughout the session — not just in the final stages when deficits start to show.

Potassium contributes to normal muscle function. Magnesium contributes to electrolyte balance. For HYROX athletes running eight 1km efforts between functional workouts, these aren't abstract benefits — they're the baseline your body draws on.
