Lewiston, ID-WA

Lewiston sits at the confluence of the Snake and Clearwater rivers in a canyon landscape with steep surrounding terrain; trail runners dominate here, with the Hell's Canyon Gruel Duathlon and the Miles for Mimosas 5K offering local options, while the rougher Northwest Series events pull serious competitors into backcountry running and cycling across the ID-WA border. Cyclists face immediate climbing out of the river valley—Hell's Canyon National Recreation Area is 30km northeast with sustained elevation gain, and the surrounding Wallowa-Whitman terrain offers alpine routes above 1500m. Road running is secondary to the canyon's natural draw for mountain-focused athletes.
