| 600 | 1h36 | 0h01 | — | 96 g | 1.1 L | 801 mg | +2h24 |
| 650 | 1h31 | 0h01 | — | 91 g | 1.1 L | 759 mg | +2h29 |

| 800 | 1h17 | 0h01 | — | 77 g | 0.9 L | 646 mg | +2h43 |
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.
