Run Ohio Races Christmas 1.5 mile fun run 5k, 10k, 15k

Run Ohio Races Christmas 1.5 mile fun run 5k, 10k, 15k is held in Fairborn, Ohio, on December 26, 2026. Four formats all set off together at 8:00 a.m.: a 5K (3.1 miles), a 10K (6.2 miles) and a 15K (9.3 miles), each run on trail, plus a 1.55-mile fun run. The shared start means everyone is on the course at the same time regardless of distance.

Trail underfoot changes the calculation: expect your pace per mile to be slower than on road, and judge the effort by how you feel rather than by the watch. The 15K is the standout here, long enough to reward genuine endurance without demanding a marathon build; six to eight weeks with a weekly long run of eight to ten miles, some of it off pavement, prepares you well. The fun run is the family option and needs nothing at all.
