The Experience
The Koala Bottle Harbison Half Marathon and 5K invites runners to experience the natural beauty of Harbison State Forest in Columbia, South Carolina. This annual event, now in its second year, promises a "true South Carolina experience" with a course described as "somewhat challenging" and "Fabulously Hot On The Trail."
Runners can expect a start in the early morning, aiming to beat the typical July heat that averages between 73–90°F. The race, which typically sees around 182 finishers and draws participants from about 12 states, offers a T-shirt and a finisher's medal to all participants. While the field size is modest, the event is growing, with about 17% of runners returning in subsequent years.
Packet pickup is available on Saturday afternoon or race morning. The half marathon begins at 7:00 AM, followed by the 5K at 7:10 AM, both starting from Harbison State Forest.
