The Blacktooth Challenge nearly a myth, starts in Sheridan, Wyoming at Blacktooth Brewing and travels roughly 40 miles, to get to the top of Blacktooth Mountain at 13,007 feet. 28 extremely rough miles on bike with over 5,700 feet of gain, to get to the trailhead to hike/trail run another 12 miles. Then all back down as fast as possible!
