There is a trail race on this route that has typically been held in August and perhaps September. Supported FKT attempts need to better the course record for that race and any CR on the Strava segment for this route. Unsupported attempts should improve on Strava segment times that were not set on race day.

Trail description from Alaska State Parks trail guide:

Route Starts South of Cedar Breaks National Monument (Blowhard TH), dropping down into Ashdown Gorge via Potato Hollow Trail, then connecting to Rattlesnake Trail back to the North end of Cedar Breaks.  The route circumvents Cedar Breaks in a "C" shape.  Route can be done from N to S, S to N, and repeated as many times as you'd like.
