Get ready to set a personal record or complete the ultimate fall marathon tune-up! Staged out of scenic Phegley Park in downtown Morrow, OH, the Little Miami Half Marathon and 10K takes you on a fast, smooth, out-and-back journey along the paved Little Miami Scenic Trail. With little-to-no elevation gain and ample tree canopy shade along the river, it's one of Southwest Ohio's favorite late-summer racing traditions.
