Zugspitz Ultra Trail - Grainau 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 1h53 to 1h08. 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.
| UTMB® Index | Estimated time | Night hours | Carbs | Fluid | Sodium | Cut-off margin |
|---|---|---|---|---|---|---|
| 500 | 1h53 | — | 113 g | 1.3 L | 942 mg | +2h07 |
| 550 | 1h46 | — | 106 g | 1.2 L | 883 mg | +2h14 |
| 600 | 1h36 | — | 96 g | 1.1 L | 800 mg | +2h24 |
| 650 | 1h26 | — | 86 g | 1 L | 717 mg | +2h34 |
| 700 | 1h19 | — | 79 g | 0.9 L | 658 mg | +2h41 |
| 750 | 1h13 | — | 73 g | 0.9 L | 608 mg | +2h47 |
| 800 | 1h08 | — | 68 g | 0.8 L | 567 mg | +2h52 |
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.
