Between a UTMB® Index of 500 and 800, the estimated finish time on this race runs from 3h30 to 2h02, and the aid-station stop budget from 0h08 to 0h03. The longer the race, the more stops weigh: this is time you should plan to spend standing still, not only running.
Source| UTMB® Index | Estimated time | Of which stops | Night hours | Carbs | Fluid | Sodium | Cut-off margin |
|---|---|---|---|---|---|---|---|
| 500 | 3h30 | 0h08 | — | 210 g | 2.5 L | 1,750 mg | +3h30 |

| 800 | 2h02 | 0h03 | — | 122 g | 1.4 L | 1,017 mg | +4h58 |
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.
