The 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 benefits Trails for Illinois, the tiny non-profit that works to improve the Hennepin Canal State Trail and other non-motorized trails statewide. You are running to benefit the Illinois trails we love.
