50K

The Middle Fork 50K is a long, scenic river-valley ultra that combines classic Middle Fork singletrack with segments of the CCC trail network and short forest-road connectors. The course is runnable in many places, but it’s still a true PNW endurance day — long miles in the woods with constant scenery and a few key junctions to manage.

Course notes from NWTR: the 50K route crosses Burnt Boot Creek, which typically can be waded; organizers often build at least a minimal log bridge for those comfortable with a dry-foot crossing.

Starts at the Middle Fork Trailhead and uses the CCC connector + CCC trail out-and-back before heading onto the Middle Fork Trail. Continues to Dingford Creek junction (Aid B), then to the bridge near Goldmyer (Aid C), with a forest-road segment and return back across to Aid C. Finishes by returning along Middle Fork Trail past Aid B to the trailhead.
