About the Idaho Falls Marathon
A local nonprofit organizes this Idaho road marathon alongside separate half-marathon and 5K events. The full is also part of a regional Triple Crown, but retains its own race identity and entry.
Course
The 26.2-mile road route combines open agricultural roads with stretches near the Snake River Greenbelt. Long exposed sections can magnify wind, while the riverside approach provides a scenic change late in the race.
Race-day weather
Late July in Idaho Falls often begins cool and dry before bright sun raises temperatures. High-desert air, wind and exposure make early hydration important even without heavy humidity.
