Between a UTMB® Index of 500 and 800, the estimated finish time on this race runs from 2h25 to 1h27, and the aid-station stop budget from 0h06 to 0h02. 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 | 2h25 | 0h06 | — | 145 g | 1.7 L | 1,208 mg | +3h35 |

| 800 | 1h27 | 0h02 | — | 87 g | 1 L | 725 mg | +4h33 |
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.
