Restonica Trail - Ultra-Trail® di Corsica: 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 33h58 to 18h18. 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 380, the overall cut-off of 40h01 is no longer reachable at the estimated pace.
| UTMB® Index | Estimated time | Night hours | Carbs | Fluid | Sodium | Cut-off margin |
|---|---|---|---|---|---|---|
| 500 | 33h58 | 18 | 2,038 g | 23.8 L | 16,983 mg | +6h03 |
| 550 | 29h53 | 15.9 | 1,793 g | 20.9 L | 14,942 mg | +10h08 |
| 600 | 26h47 | 12.8 | 1,607 g | 18.7 L | 13,392 mg | +13h14 |
| 650 | 23h32 | 9.5 | 1,412 g | 16.5 L | 11,767 mg | +16h29 |

| 800 | 18h18 | 8 | 1,098 g | 12.8 L | 9,150 mg | +21h43 |
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.
