Riders may start an Individual Time Trial (ITT) at any time. Trackleaders registration is separate from expressing interest by email and will be announced when available.
Not an organized event. No entry fee, sponsor, aid station, course marshal, medical support, traffic control, prize money or guaranteed assistance. Riders independently choose whether and how to attempt the route.
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.

Tracking informationSafety is your responsibility.
Wildfire, smoke, severe weather, isolation, traffic, wildlife, equipment failure, navigation mistakes and delayed rescue are real risks. Check current conditions and closures, carry suitable emergency communication, and leave a plan with someone you trust.
A tracker does not guarantee monitoring or rescue.
