About the Grandview Half Marathon

The Grandview Half Marathon is held in December at Columbus Youth Camp, west of Columbus, Indiana. The course is on paved county roads: a 250-foot descent over the first 1.9 miles along Wolf Creek to a turnaround and back up, then a 200-foot drop to Grandview Lake, a loop of the lake over rolling hills and a final climb to the finish at the camp. A 5K on the same hills runs at the same time. The Columbus Running Club lists the race on its events page.
