Julian Alps Trail Run - LAKE BLED 80K: 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 14h23 to 8h41. 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.

|---|---|---|---|---|---|---|
| 500 | 14h23 | 2.4 | 863 g | 10.1 L | 7,192 mg | +7h37 |

| 800 | 8h41 | — | 521 g | 6.1 L | 4,342 mg | +13h19 |
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.
