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

| 800 | 5h25 | — | 325 g | 3.8 L | 2,708 mg | +6h35 |
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.
