Racing in Idaho

Idaho runs a year-round race calendar, so there’s almost always a race near you. The calendar is busiest in November, May, and June, with races most often held in Boise and Sandpoint.

Races in Idaho cover the jagged Sawtooth Range and broader Rocky Mountains in the center and north, with the flatter Snake River Plain running across the south. Courses split between steep, high-altitude mountain trail ultras and flatter, high-desert road races along the plain.

Conditions vary widely by region across Idaho, 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.
