Montana runs a year-round race calendar, so there’s almost always a race near you. The calendar is busiest in October, July, and June, with races most often held in Missoula, Bozeman, Billings, and Ennis.
Races in Montana split between the Rocky Mountains and their forested valleys in the west and the wide-open Great Plains to the east. That divide produces steep, high-altitude mountain trail ultras on one side of the state and flat, fast prairie road races on the other.
Conditions vary widely by region across Montana, so weather lives where it’s accurate — each race page shows its typical race-day high, low, and rain chance from NOAA climate normals for that venue and date.
