25 and 50 mile fatass style run along the wild and Scenic North Fork of the American River. Expect roughly 10,000' of climbing for the 25 mile and 20,000' for the 50, with a good amount of bushwhacking and route finding thrown in for good measure. Free to enter, but the rule is that you have to wait at the finish for at least one runner to come in.

The forest service has confirmed that we don't need a permit as long as we keep it small, so registration for both distances combined will be limited to 40 people. Since portions are off trail, I'm not going to post the map until the week before the event, but it will start and finish at the Shirttail Creek Campground near Foresthill, CA and go up and down out of the canyon using Euchre Bar, Pioneer Mine, Ebeneezer's highway, Green Valley, Mumford Bar, and Italian Bar. There will be one location for drop bags and crew to meet you that you will pass through twice.
