- Increase carbohydrate intake to 7–10g per kg body weight per day
- Focus on easily digestible sources: pasta, rice, potatoes, white bread
- Reduce fiber and fat intake 24–48 hours before

- Test all nutrition during training rides first
Hydration

Hydration & Electrolytes
Your fluid targetCalculate in Tab 1
