Rothrock - 50K: 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 7h43 to 4h32, and the aid-station stop budget from 0h15 to 0h05. The longer the race, the more stops weigh: this is time you should plan to spend standing still, not only running.
Source| UTMB® Index | Estimated time | Of which stops | Night hours | Carbs | Fluid | Sodium | Cut-off margin |
|---|---|---|---|---|---|---|---|
| 500 | 7h43 | 0h15 | — | 463 g | 5.4 L | 3,861 mg | +4h24 |
| 550 | 7h00 | 0h12 | — | 420 g | 4.9 L | 3,499 mg | +5h07 |

| 800 | 4h32 | 0h05 | — | 272 g | 3.2 L | 2,265 mg | +7h35 |
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.
