Hour by hour, from the start to the estimated finish
Local race times (America/Indiana/Indianapolis). This race does not publish its cut-off: the finish is estimated for a slow runner, so the last columns are indicative.
Section-by-section forecasts for Tecumseh 50K 2026, calculated at the estimated passing time: feels-like temperature, rain or snow, wind and thunderstorms. Three models — AROME (Météo-France), ICON (DWD) and ECMWF IFS — served from the finest to the farthest-reaching.
The weather for the entire race, by 4-hour slots, at the start and at each aid station — to know when rain arrives and which pass gets windy, whatever your pace.
Forecast, not guaranteed: in the mountains a model describes a grid of several hundred meters, not the slope you're on.
