Between a UTMB® Index of 500 and 800, the estimated finish time on this race runs from 14h54 to 8h57. These times include aid-station stops: they come from real durations between two timing points, and this race's timing does not measure stops separately.

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.
