|---|---|---|---|---|---|---|
| 500 | 2h54 | 1 | 174 g | 2 L | 1,450 mg | +4h06 |
| 550 | 2h36 | 1 | 156 g | 1.8 L | 1,300 mg | +4h24 |

| 800 | 1h52 | 1 | 112 g | 1.3 L | 933 mg | +5h08 |
Figures based on 60 g of carbohydrate, 700 mL of fluid and 500 mg of sodium per hour, "average" preparation and mild conditions (15–25 °C). Above 25 °C, count on roughly 900 mL/h and 700 mg/h. Carbohydrate intake is trained: 60 g/h is a floor, 90 g/h assumes a glucose-fructose blend and a gut used to it.
