| 550 | 6h17 | 0h12 | — | 377 g | 4.4 L | 3,140 mg |
| 600 | 5h42 | 0h10 | — | 342 g | 4 L | 2,846 mg |
| 650 | 5h11 | 0h08 | — | 311 g | 3.6 L | 2,592 mg |

| 750 | 4h30 | 0h06 | — | 270 g | 3.1 L | 2,248 mg |
| 800 | 4h12 | 0h05 | — | 252 g | 2.9 L | 2,098 mg |
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.
