MO' Cowbell has the fastest, flattest course in the St. Louis region! This USATF certified course takes off from the banks of Missouri River in St. Charles, Missouri, and takes runners on a winding course through the area's most historic neighborhoods, then one of its most progressive locales in New Town. The race returns back to the start/finish where runners head north on the Katy Trail for a fast up-and-back route. The finish line will have LOTS of ringing cowbells to cheer runners on! Don't miss it!
