Idaho Falls, ID

Idaho Falls sits where the Snake River cuts through sagebrush plateau at 4,700 feet elevation, creating a surprisingly technical running and cycling landscape. The Idaho Falls Marathon & Half follows the river corridor through town, while cyclists tackle serious elevation gain on the surrounding bench roads—the HeART of Idaho Century Ride and Angry Horse Gravel Race both exploit the rolling terrain and dirt routes that radiate east and south from town. Winter running is cold and snowy, but spring through fall offers fast high-altitude racing with dramatic views of the Teton Range to the southeast.
