Little Miami Half Marathon and 10K 2026

The Little Miami Half Marathon and 10K begins and ends in Morrow, Ohio, a short distance east of Kings Island. Two race distances are available: a half marathon and a 10K, both including chip timing and a tech shirt. The half marathon serves as a quick tune-up for runners training for autumn marathons or half marathons. The course uses a shaded bike path alongside the Little Miami River, a benefit during humid Ohio summer conditions. Participants will go through South Lebanon and Kings Mills before heading back to Morrow. The half marathon course is level and swift, suitable for runners seeking consistent pacing or using the event as a structured training run.
