| 550 | 26h59 | 1h46 | 11 | 1,619 g | 18.9 L | 13,488 mg |
| 600 | 24h47 | 1h27 | 10.8 | 1,487 g | 17.3 L | 12,389 mg |
| 650 | 22h42 | 1h12 | 8.7 | 1,362 g | 15.9 L | 11,351 mg |
| 700 | 20h51 | 1h00 | 6.9 | 1,251 g | 14.6 L | 10,429 mg |

| 800 | 17h54 | 0h44 | 3.9 | 1,074 g | 12.5 L | 8,948 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.
