StumpJump 50k
From Wikipedia, the free encyclopedia
The StumpJump 50k is an ultramarathon in the Southeastern United States that features a grueling course of extreme elevation changes and technical trail sections. The annual event takes place the first Saturday in October on the Signal Mountain, Tennessee, portion of the Cumberland Trail. In 2007 the race field was limited to 400 participants to limit the impact on this wilderness area. The race benefits the Cumberland Trail Conference, and in 2007, raised $4,000 for CTC's for trail-building and maintenance programs.
