🏃 Run Conditions

Heat & Humidity Impact

At 32°C and 70% humidity, the run will be brutal. Start conservative — go out 10-15s/km slower than race pace. Walk through every aid station. Pour water on your head. This is where races are lost.

Run Course Terrain

road surface, flat profile with ↑0m of elevation gain. This is a 2-lap course — use the first lap to find your rhythm, then execute on the second.

💧 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 32°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.
