Between a UTMB® Index of 500 and 800, the estimated finish time on this race runs from 1h37 to 0h59. These times include aid-station stops: they come from real durations between two timing points, and this race's timing does not measure stops separately.
Source| UTMB® Index | Estimated time | Night hours | Carbs | Fluid | Sodium | Cut-off margin |
|---|---|---|---|---|---|---|
| 500 | 1h37 | 0.6 | 97 g | 1.1 L | 808 mg | +1h23 |
| 550 | 1h28 | 0.5 | 88 g | 1 L | 733 mg | +1h32 |
| 600 | 1h21 | 0.4 | 81 g | 0.9 L | 675 mg | +1h39 |

| 800 | 0h59 | — | 59 g | 0.7 L | 492 mg | +2h01 |
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.
