Runners start the out-and-back course for the Columbus Half Marathon at Sycamore Fields in Three Creeks Metro Park. From there, runners head onto the Alum Creek and Blacklick Greenway Trails for the first 6.5 miles, reaching the midway point of the race just before the Winchester Pike crossing. Once they reach the mid-way point, runners make the turnaround and head back to Sycamore Fields for the race finish.
