💧 Hydration & Nutrition Strategy
Before the Race
Hydrate aggressively in the 48 hours before. Pre-load with sodium the night before. Aim for clear urine on race morning.
On the Bike
Aim for 750ml–1L per hour. Start drinking in the first 15 minutes. Target 60–90g carbs/hour (gels + drink). At 25°C, you'll lose more fluid than you can absorb — minimize the deficit.
On the Run
Take fluid at EVERY aid station. Alternate water and sports drink. Pour water on your head and wrists to cool down. Walk through stations if needed — the 10 seconds you spend is worth it.
