The challenge
Big country. Simple rules.
The loop begins and ends in Boise and crosses roughly 400 miles of Idaho terrain, with nearly 50,000 feet of climbing.
Expect forest roads, singletrack, river valleys, alpine weather, resupply uncertainty, hike-a-bike and long stretches where your decisions are entirely your own.
