Get ready for one of Southern Indiana's most distinctive running experiences! Starting at the Boys & Girls Club of Crawford County on S 2nd Street, you'll head down SR 64 past Marengo Cave and through charming downtown Marengo before entering an underground warehouse at the 1-mile mark for a unique cave-like section complete with hairpin turns and smooth terrain. This one-of-a-kind course combines rolling hills, scenic small-town views, and the bonus of staying cool in the naturally 54-degree underground passage—making it truly the coolest July 5K around.
