The MO' Cowbell Marathon starts and finishes in Frontier Park, bordered by the Missouri River on one side and historic Main Street St. Charles on the other. The flat, fast course winds its way out toward New Town St. Charles for a loop around the very unique neighborhood there before heading back toward Frontier Park. The second half runs north along the Katy trail for a quick down and back flat course.
We also have a Half Marathon, Half Marathon Relay and 5K race!
