Organiser's Description
The most unique race in Southern Indiana! As underground temperatures year-round are 54 degrees, this will undoubtedly be the coolest July race around.
The course will start Marengo Boys and Girls Club proceeding down SR 64 passing Marengo Cave. It then heads directly to the underground tour at mile 1 doubling back to finish just outside at the festival. Features include the underground, rolling hills, and scenic small town Indiana charm. By far the coolest both in temperature and in novelty.
The warehouse features several back and forth hairpin turns eventually leading down a corridor of offroad-like but smooth terrain. The entry point is shortly after the 1 mile interval where the indoor portion is right at 2 miles in total. Inside you will find good lighting, good temperature, and fast and flat terrain. A destination race that will offer major relief from the hot summer and a scene like none other.
