Endurance Racing in Idaho

Idaho's rugged mountain terrain and pristine wilderness make it a haven for trail runners, mountain bikers, and adventure-seeking endurance athletes. The Sawtooth Mountains, Boise foothills, and Sun Valley ski areas transform into trail running courses each summer. Ironman 70.3 Boise has become a cornerstone triathlon event, while the state's rivers and lakes host growing open water swimming events. Boise's urban trail system — with over 190 miles of paved paths along the Boise River — creates a year-round training ground for runners and cyclists. The state's gravel roads through ranch country are increasingly attracting cycling events. Idaho's race season runs May through October, with peak conditions in the dry, warm months of July and August.
