Xtrail - Xtrail 100K: times, aid-station stops and fuelling needs by UTMB® Index
Between a UTMB® Index of 500 and 800, the estimated finish time on this race runs from 16h37 to 9h50. 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.
SourceBelow a UTMB® Index of roughly 320, the overall cut-off of 24h00 is no longer reachable at the estimated pace.
| UTMB® Index | Estimated time | Night hours | Carbs | Fluid | Sodium | Cut-off margin |
|---|---|---|---|---|---|---|
| 500 | 16h37 | 3 | 997 g | 11.6 L | 8,308 mg | +7h23 |
| 550 | 15h05 | 3 | 905 g | 10.6 L | 7,542 mg | +8h55 |
| 600 | 14h06 | 3 | 846 g | 9.9 L | 7,050 mg | +9h54 |
| 650 | 13h12 | 3 | 792 g | 9.2 L | 6,600 mg | +10h48 |
| 700 | 12h12 | 3 | 732 g | 8.5 L | 6,100 mg | +11h48 |
| 750 | 11h02 | 3 | 662 g | 7.7 L | 5,517 mg | +12h58 |
| 800 | 9h50 | 3 | 590 g | 6.9 L | 4,917 mg | +14h10 |
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.
