Hong Kong 100: times, aid-station stops and fuelling needs by UTMB® Index

Below a UTMB® Index of roughly 355, the overall cut-off of 30h15 is no longer reachable at the estimated pace.

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.
