Example Output
Marathon Race Week Fueling Plan
Wednesday to Friday: Carb Build
Target 7-9g carbohydrate per kg bodyweight while tapering training volume. Keep fiber moderate, avoid experimenting with unfamiliar foods.
Race Morning
- 3 hours pre-race: bagel with honey, banana, and 500-700ml electrolyte drink
- 20 min pre-race: 1 gel + a few sips of water
In-Race Fueling
| Time | Fuel | Notes |
|------|------|-------|
| 0:35 | 1 gel (25g carbs) | Wash down with water |
| 1:10 | Sports drink | Sip steadily, don't chug |
| 1:45 | 1 gel + sodium | Increase if weather is hot |
| 2:20 | 1 gel | Only if tolerated in training |
Biggest Mistake to Avoid
Overeating the night before and under-fueling the morning of the race. Glycogen loading happens over days, not in one giant pasta dinner.
Tips for Best Results
- 💡Use products you have already tested in long runs, race day is not the time for culinary roulette
- 💡Share expected weather, because sodium and hydration needs change fast in heat
- 💡Ask for both metric and imperial measurements if you usually mix systems during training
