The Little Miami Half Marathon and 10K is a flat and fast scenic half marathon run along the banks of the Little Miami River. Are you training for a fall marathon or half marathon? This race is a perfect tune-up! Plus, the entire course is run on a shaded bike path, which is a big bonus during Ohio’s humid summer months!
The race starts and finishes in Morrow, OH, just a few miles east of King’s Island, and travels through South Lebanon and Kings Mills. A killer tech shirt, chip timing and a party-like atmosphere at the finish are guaranteed to make this race a kickin’ good time!
