IRONMAN 70.3 Boise

IRONMAN 70.3 Boise is a half-iron distance triathlon in Boise, Idaho, combining a high-desert reservoir swim with rolling foothills terrain and a shaded riverside run. The race begins with a single-loop 1.2-mile swim in the pristine Barclay Bay of Lucky Peak Reservoir, followed by a 56-mile rolling bike course that descends from the reservoir into downtown Boise through rural roads and neighborhood streets, and concludes with a flat two-loop 13.1-mile run along the tree-lined Boise River Greenbelt finishing at Julia Davis Park. Serving as a qualifying race for the IRONMAN 70.3 World Championship, the event is notable for stunning views of the Boise foothills and city skyline, free shuttles from downtown to the swim start, and a welcoming downtown finish atmosphere.
