Start & Time Limit

Elk River Hiking Trail. Accurately measured forest trail winding through unique limestone bluffs, rock formations & picturesque vistas. Mostly single-track, out & back, very rocky, no long hills. Home of the "legendary" FlatRock 50/25K's and the "infamous" FlatRock 101K.

Aid Stations

3 Aid Stations in the 25K and 1 (turnaround) in the 12K. Aid stations are approximately 3.5-4 miles apart, are all unmanned, with only water available. No cups will be available, so you MUST carry a handheld bottle with you on the course. If you need fuel (calories) of any type, YOU are responsible to pack it with you, as there will be none available on the course.

Check-In/Staging Area

Race headquarters will be located in the Outlet Channel Group Shelter (north side of the Elk City Lake dam). Race bib (shirt) pick-up will be from 9:30:10:30 AM on Saturday morning January 7, 2017. Map to the staging area can be found by clicking the link below:
