Race Strategy

Swim: Start smooth. Clear water helps sighting. Find your rhythm. Consider using anti-fog swimming goggles for optimal visibility.

Nutrition: Target 60–90g carbs/hour on bike. Practice it. Electrolytes are crucial. Carry backups.

- Wide gearing recommended for the climb.
- Comfortable trisuit, sunscreen, sunglasses.
