The 2018 Hennepin Hundred

  • Sinissippi Park 1100 Sinnissippi Road Sterling, IL, 61081 United States (map)

Flat and fast, the Hennepin Hundred ultra-marathon follows the 104-mile Hennepin Canal State Trail, Illinois’ longest multi-use trail, across historic locks and lift bridges, past the autumn corn, picturesque farms and postcard towns of northwest Illinois.

It’s a race that engages you in something larger. Running the Hennepin Hundred raises funds that help the trail's tiny state park staff repair, maintain and improve the trail. You are running to benefit the trail we love!
