The Smoke ‘n’ Fire 400 is a self-supported mountain bike route that highlights some of the great diversity of Idaho’s geography including prolific river systems, mountain ranges, and abundant wildlife. This 400ish mile loop features nearly 41,000 feet of climbing, big expanses, grand views, backcountry forest roads, the Centennial and the Harriman Trail, great single-track, occasional pavement, and a touch of hike-a-bike.

The route traverses several scenic mountain ranges and if you’re not climbing you’ll be descending.

There is no registration fee, no support and no prize money. SPOT tracker use is not mandatory, but encouraged and live tracking of the event will be provided by Trackleaders.

The Smoke ‘n’ Fire route travels through remote areas, however, there are sufficient resupply opportunities available. Besides the physical challenge, there are mental challenges to this route and it is also a great test of your bikepacking kit and gear.

This is a self-supported event so please read the rules and be prepared for the unexpected.
