Eiger Ultra Trail - E101 - Ultra Trail: 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 21h46 to 13h09. 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 370, the overall cut-off of 25h00 is no longer reachable at the estimated pace.
| UTMB® Index | Estimated time | Night hours | Carbs | Fluid | Sodium | Cut-off margin |
|---|---|---|---|---|---|---|
| 500 | 21h46 | 7.8 | 1,306 g | 15.2 L | 10,883 mg | +3h14 |
| 550 | 19h49 | 5.8 | 1,189 g | 13.9 L | 9,908 mg | +5h11 |
| 600 | 17h55 | 3.9 | 1,075 g | 12.5 L | 8,958 mg | +7h05 |
| 650 | 16h26 | 3 | 986 g | 11.5 L | 8,217 mg | +8h34 |
| 700 | 15h35 | 3 | 935 g | 10.9 L | 7,792 mg | +9h25 |

| 800 | 13h09 | 3 | 789 g | 9.2 L | 6,575 mg | +11h51 |
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.
