MMM2026: 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 39h38 to 24h03, and the aid-station stop budget from 6h24 to 1h15. The longer the race, the more stops weigh: this is time you should plan to spend standing still, not only running.
Below a UTMB® Index of roughly 570, the overall cut-off of 36h00 is no longer reachable at the estimated pace.
| UTMB® Index | Estimated time | Of which stops | Night hours | Carbs | Fluid | Sodium | Cut-off margin |
|---|---|---|---|---|---|---|---|
| 500 | 39h38 | 6h24 | 11.6 | 2,378 g | 27.7 L | 19,815 mg | −3h38 |
| 550 | 36h58 | 5h21 | 11 | 2,218 g | 25.9 L | 18,484 mg | −0h58 |
| 600 | 33h46 | 4h12 | 11 | 2,026 g | 23.6 L | 16,887 mg | +2h14 |
| 650 | 30h09 | 2h53 | 11 | 1,809 g | 21.1 L | 15,079 mg | +5h51 |
| 700 | 28h05 | 2h10 | 11 | 1,685 g | 19.7 L | 14,039 mg | +7h55 |
| 750 | 26h08 | 1h38 | 11 | 1,568 g | 18.3 L | 13,068 mg | +9h52 |
| 800 | 24h03 | 1h15 | 10.1 | 1,443 g | 16.8 L | 12,028 mg | +11h57 |
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.
