Going to run this as a race May 25, 2018 and would love to have others along for the ride.
Almo, Idaho to Beaver Dam, Arizona - 450 miles, 17k climbing. (Fast route, could definitely be done in 2 days, 3-4 comfortably)
Grassroots event, no fees, self-supported. Official time is based on timestamped receipts from the Tracy General Store in Almo and Beaver Dam Station in Beaver Dam.
Couple buddies and I have been pre-riding the route for the past couple years. Great small towns along the route, couple ghost towns, a couple more almost ghost towns, and lots of wildlife. Almost always see wild horses.
Water logistics are key to this ride. (Think desert scene from The Good, The Bad, and The Ugly... "If you save your breath I feel a man like you can manage it...")
