SMT15: 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 2h21 to 1h38, and the aid-station stop budget from 0h03 to 0h01. 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 | 2h21 | 0h03 | 1 | 141 g | 1.6 L | 1,176 mg |
| 550 | 2h09 | 0h02 | 1 | 129 g | 1.5 L | 1,078 mg |
| 600 | 2h01 | 0h02 | 1 | 121 g | 1.4 L | 1,008 mg |
| 650 | 1h54 | 0h02 | 1 | 114 g | 1.3 L | 954 mg |
| 700 | 1h49 | 0h02 | 1 | 109 g | 1.3 L | 907 mg |
| 750 | 1h44 | 0h01 | 1 | 104 g | 1.2 L | 865 mg |
| 800 | 1h38 | 0h01 | 1 | 98 g | 1.1 L | 817 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.
