Elk-King 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 7h34 to 4h46, and the aid-station stop budget from 0h16 to 0h06. The longer the race, the more stops weigh: this is time you should plan to spend standing still, not only running.
| UTMB® Index | Estimated time | Of which stops | Night hours | Carbs | Fluid | Sodium |
|---|---|---|---|---|---|---|
| 500 | 7h34 | 0h16 | — | 454 g | 5.3 L | 3,785 mg |
| 550 | 6h49 | 0h13 | — | 409 g | 4.8 L | 3,409 mg |
| 600 | 6h13 | 0h11 | — | 373 g | 4.4 L | 3,107 mg |
| 650 | 5h47 | 0h09 | — | 347 g | 4 L | 2,892 mg |
| 700 | 5h24 | 0h08 | — | 324 g | 3.8 L | 2,702 mg |
| 750 | 5h06 | 0h07 | — | 306 g | 3.6 L | 2,547 mg |
| 800 | 4h46 | 0h06 | — | 286 g | 3.3 L | 2,383 mg |
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.
