| UTMB® Index | Estimated time | Night hours | Carbs | Fluid | Sodium | Cut-off margin |

| 550 | 14h03 | 1 | 843 g | 9.8 L | 7,025 mg | +5h57 |
| 600 | 12h41 | 1 | 761 g | 8.9 L | 6,342 mg | +7h19 |
| 650 | 11h25 | 1 | 685 g | 8 L | 5,708 mg | +8h35 |

| 800 | 9h06 | 1 | 546 g | 6.4 L | 4,550 mg | +10h54 |
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.
