Race Info

Gorgeous paved paths, stunning views and rolling country roads make this course the Marathon to remember!

Rend Lake, IL, located in the heart of southern Illinois, is a natural haven for wildlife and a recreational haven for visitors. Rend Lake consists of 18,900 acres of water and 20,000 acres of land. Campers will delight in the nearly 800 sites found in 5 public campgrounds on Rend Lake. Boaters are provided access to the lake through the numerous boat ramps. Beaches, picnic sites and trails provide the perfect backdrop for outdoor fun.

The course then will take you across the lake for one of the best panoramic views in Illinois, before connecting to the bike path which passes South Sandusky Beach, the Marina, Rend Lake Visitors Center, the amazing spillway and dozens of other spectacular views of Rend Lake. From there you will continue on country roads winding through beautiful vistas including both Lake Hamilton and Lake Benton. Finally you will get back on the bike path and end at the stunning North Marcum Beach.

We can't wait to see you finish your next great adventure with us!
