Monte Rosa Walserwaeg - Monte Rosa Trail: 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 19h56 to 11h33, and the aid-station stop budget from 0h34 to 0h08. The longer the race, the more stops weigh: this is time you should plan to spend standing still, not only running.

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.
