MaXi-Race - Marathon eXpérience: 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 5h27 to 3h33, and the aid-station stop budget from 0h12 to 0h04. 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 | Cut-off margin |
|---|---|---|---|---|---|---|---|
| 500 | 5h27 | 0h12 | 1 | 327 g | 3.8 L | 2,722 mg | +3h18 |
| 550 | 4h56 | 0h10 | 1 | 296 g | 3.5 L | 2,464 mg | +3h49 |
| 600 | 4h35 | 0h08 | 1 | 275 g | 3.2 L | 2,290 mg | +4h10 |
| 650 | 4h14 | 0h07 | 1 | 254 g | 3 L | 2,116 mg | +4h31 |
| 700 | 3h58 | 0h06 | 1 | 238 g | 2.8 L | 1,987 mg | +4h47 |
| 750 | 3h47 | 0h05 | 1 | 227 g | 2.6 L | 1,888 mg | +4h58 |
| 800 | 3h33 | 0h04 | 1 | 213 g | 2.5 L | 1,774 mg | +5h12 |
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.
