Idaho Smoke and Fire is a 400-ish-mile self-supported mountain-bike route highlighting Idaho’s rivers, mountain ranges, forests, hot springs, wildlife, and wide-open geography.
The challenge
The loop features nearly 50,000 feet of climbing, large expanses and big views, backcountry Forest Service roads, portions of the Idaho Centennial Trail and Harriman Trail, demanding singletrack, occasional pavement, and a meaningful amount of hike-a-bike.
September in Idaho can offer clear days, chilly nights, changing colors and quieter backcountry travel. Conditions can also change quickly. Smoke, wildfire, closures, storms, freezing temperatures, heat, road damage and seasonal service changes are all possible.
Independent participation
There is no entry fee, prize money, aid station, course marshal, medical support, traffic control, transportation or guaranteed assistance. Riders independently decide whether, when and how to attempt the route and remain responsible for preparation, navigation, safety, decisions and transportation.
History and name
The route is now officially known as the Idaho Smoke and Fire.
