Julian Alps Trail Run - KRANJSKA GORA 25K: 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 2h55 to 1h47. 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 | 2h55 | — | 175 g | 2 L | 1,458 mg | +3h19 |
| 550 | 2h42 | — | 162 g | 1.9 L | 1,350 mg | +3h32 |
| 600 | 2h26 | — | 146 g | 1.7 L | 1,217 mg | +3h48 |
| 650 | 2h17 | — | 137 g | 1.6 L | 1,142 mg | +3h57 |
| 700 | 2h05 | — | 125 g | 1.5 L | 1,042 mg | +4h09 |
| 750 | 1h56 | — | 116 g | 1.4 L | 967 mg | +4h18 |
| 800 | 1h47 | — | 107 g | 1.2 L | 892 mg | +4h27 |
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.
