Course and support

The course follows trails around Jenkinson Lake through pine forest and a combination of hiking and horse trails. Most routes use single-track trail around the lake, with rolling hills, shaded sections, and some technical segments but no steep altitude gains. Some distances require multiple loops around the lake.

There are two aid stations located on opposite ends of the lake (Event Center and Hazel Creek); distances over the 10K hit these stations at least once. Drop-bag service is available. Water stops and additional course markings are provided for longer loops. Restrooms are available at the event center and at multiple points along the course. All finishers receive a commemorative medal. Volunteers who assist at aid stations receive a complimentary future race entry. Visit the organization's website for the most recent information.
