| 550 | 6h09 | — | 369 g | 4.3 L | 3,075 mg | +2h36 |
| 600 | 5h38 | — | 338 g | 3.9 L | 2,817 mg | +3h07 |
| 650 | 5h11 | — | 311 g | 3.6 L | 2,592 mg | +3h34 |

| 800 | 4h12 | — | 252 g | 2.9 L | 2,100 mg | +4h33 |
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.
