I ran Crazy Horse for the first time this year, although I ran Lean Horse Ultra, which is also on the Mickelson trail. Crazy Horse is a cool race, you start at the Crazy Horse monument visitor center (inside!) and then run towards the monument. If there weren't super low clouds, the view wouldn't been very cool, you run basically right by the base of the mountain. Most of the race is on the Mickelson trail, which is crushed rock, and since it's a rail-trail, elevation gain loss is gradual. If you need crowds, you may want to look elsewhere, this is a nice smaller race. MM#1058
