The 10.4-mile loop course starts with five miles out primarily on the Willis River Trail before heading back on sections of the Cumberland Multi-use, Lost Barr Loop, Lakeside and other trails. The run is 98% trail and about 2% road. The Willis River Trail is the single-track and somewhat challenging section: the second half of the race can be run faster and more easily. There are no significant elevation changes, but you will still get about 1,000 feet of vert. The trail crosses several creeks, has numerous short hills and includes some challenging sections with fallen trees across the path and leaves, roots and mud underfoot. This map provides a general overview of the loop course but it will be wise to follow the course markings on race day and even then some runners manage to wander off course.
