Trail Races in Idaho: The 16 Races Worth Training For
Idaho is big, quiet mountain country: the Sawtooths, the Salmon River range, and the Bitterroots hold long, remote courses with real vert and real solitude. Fields tend to be small and the trail tends to be raw, so races here reward runners who are comfortable being mostly alone with the mountains for a long day.
