Elevation – 2,500 Feet 50k / 1250 Feet 25k

The 2021 Harbison 50K will be the 12th year of the race! The Harbison 50K/25K is a trail race in Columbia, SC. Runners will make their way through a wide range of trails that will be a warm welcome for the first time trail runner while giving the returning athlete a chance to break a firebreak course record! The course will have a series of directional arrows that will be placed at all intersections. Please follow all directional arrows to stay on course. In the event that you make a wrong turn please backtrack to your original spot of confusion.
Runners will access Harbison State Forest at this address: 5600 Broad River Rd Columbia, SC US 29212.From there they will follow the signs to park near the Gazebo. When you enter the front gate you will make your first left hand turn. 
The race has a cut off of 10 hours due to the State Forest Hours of operation. We are implementing a hard 5 hour first lap cutoff for the 50k runners.  However, as in year’s past, as long as the runners and the race sweep are through the last aid station before the cut off, we will wait and record everyone as an official finisher! 
Aid Station
There will be a total of 3 aid stations along the course. The first two aid stations are approximately 6 miles apart, so please ensure that you have the necessary hydration and nutrition for the distance. There will be Tailwind, Water, Coke, Mountain Dew and Ginger Ale at the aid stations with an assortment of cookies, chips, crackers, etc. 

Aid Station 1 (mile 6) and 4 (mile 22): Midlands Mountain. This aid stations is located just before the Midlands Mountain

Aid Station 2 (mile 12) and 5 (mile 28): Firebreak Trail, this aid station is near the cell phone tower
