Summit climbs are the ultimate test of muscular endurance. Unlike short bursts of effort, climbing steadily for hours drains your body of fluids and electrolytes. Smart nutrition helps you sustain power on the ascent and manage fatigue at altitude.

Little and often works best. Taking small carb doses every 30–45 minutes helps maintain steady energy levels and prevents the sharp dips that can slow your pace during long ascents.

Higher altitude and prolonged effort increase fluid and electrolyte losses - even if you're feeling the chill at the top. Replacing electrolytes alongside fluids helps support overall performance throughout the climb.

Summit-day nutrition is only part of the bigger picture. How you fuel before and after makes a huge difference to your training and recovery.
