Between a UTMB® Index of 500 and 800, the estimated finish time on this race runs from 13h33 to 8h21, and the aid-station stop budget from 0h46 to 0h16. The longer the race, the more stops weigh: this is time you should plan to spend standing still, not only running.
| UTMB® Index | Estimated time | Of which stops | Night hours | Carbs | Fluid | Sodium |
|---|---|---|---|---|---|---|
| 500 | 13h33 | 0h46 | — | 813 g | 9.5 L | 6,772 mg |
| 550 | 12h30 | 0h38 | — | 750 g | 8.8 L | 6,252 mg |
| 600 | 11h10 | 0h30 | — | 670 g | 7.8 L | 5,586 mg |
| 650 | 10h20 | 0h25 | — | 620 g | 7.2 L | 5,168 mg |
| 700 | 9h34 | 0h21 | — | 574 g | 6.7 L | 4,783 mg |

| 800 | 8h21 | 0h16 | — | 501 g | 5.8 L | 4,171 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.
