About MO’ Cowbell

The MO’ Cowbell race course highlights the area with a trip through the heart of New Town just past halfway before heading back toward the finish in Frontier Park between Historic Main Street and the Missouri River. The route is flat for nearly ten miles before a two mile hilly stretch along the Little Hills Expressway. The last mile of the race is downhill heading toward the park.
