Course Description

The Stillhouse 100k trail run consists of an out-and-back of the cult classic, point-to-point Upchuck 50k that runs on the technically challenging single track of the Cumberland Trail. This course has huge climbs and descends into Soddy Creek, Possum Creek, and Rock Creek. One of the best 50k courses you will ever do, the “double” will easily be one of the harder 100k courses in the Southeast. This is a serious endeavor and possibly your most challenging 100k effort. There will only be three aid stations outbound--roughly every 10 miles. There will be a required equipment/gear list. With close to 12,000ft of elevation gain, this is a difficult run and will not be open for beginner ultra runners. It is the perfect course to test the mettle of those seasoned ultra runners looking to take the next step towards a 100 miler. Registration will be capped at 125 participants and prerequisite experience will be required and scrutinized.

Cut off is 19 hours!
