About the MO' Cowbell Half Marathon
MO' Cowbell's nonprofit weekend gives the half its own entry, scoring and course within a four-distance program in St. Charles.
Course
Nearly ten flat miles precede a hilly Little Hills Expressway segment, then the final mile descends toward Frontier Park and Main Street.
Race-day weather
Early November is often cool, but exposed riverfront miles can be windy and a cold rain may make the late hills feel sharper.
