Think Green! This is the 18th year for the Louisville St. Patrick's Day 5K. Start the spring out with a run and the Ohio Challenge Series with something green. This event is presented by the Louisville High School Boys & Girls Cross Country Program. The 5K course is mostly flat. Starting in front of Louisville High School and winding though the scenic Metzger Park, along the Nickleplate Trail and finishing back at the high school. As always we will have soup and other refreshment afterwords.
