Between a UTMB® Index of 500 and 800, the estimated finish time on this race runs from 6h01 to 3h37. 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 | 6h01 | — | 361 g | 4.2 L | 3,008 mg | +2h59 |
| 550 | 5h25 | — | 325 g | 3.8 L | 2,708 mg | +3h35 |
| 600 | 5h05 | — | 305 g | 3.6 L | 2,542 mg | +3h55 |
| 650 | 4h32 | — | 272 g | 3.2 L | 2,267 mg | +4h28 |
| 700 | 4h09 | — | 249 g | 2.9 L | 2,075 mg | +4h51 |
| 750 | 3h54 | — | 234 g | 2.7 L | 1,950 mg | +5h06 |
| 800 | 3h37 | — | 217 g | 2.5 L | 1,808 mg | +5h23 |
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.
