The Guzzler Ultra 100: 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 18h32 to 10h54, and the aid-station stop budget from 1h03 to 0h21. 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.

In the 2027 ranking

The Guzzler Ultra 100 is 105 km and 3,983 m of elevation gain, that's 145 km-effort: category L, among 87 races in 2027. Its time limit of 28 h requires a minimum speed of 3.8 km/h: rank 25 out of 83 of the widest cut-off times in L.
