The inspiration for the Dunes race was that the midwest region of America does not have a foreboding endurance challenge that is dictated by the natural landscape. We have snow and cold weather but we don’t have a lot of events that take place on challenging natural obstacles that truly challenge our abilities to failure.

Enter the massive sand dunes along Lake Michigan that have taken 1000s of years to create, yet only take 24 hours to destruct and reconstruct a new version of ourselves.

The route is about 60% sand, 20% trail, 20% other. The 3 Dunes account for the Challenge and serve as the 3 main targets you will have to summit on each lap.
