The Hennepin Hundred is Illinois’ only point-to-point, all-trail ultramarathon, a true Illinois adventure from Sterling, Illinois on the Rock River to Colona, Illinois near the mighty Mississippi, along the historic and beautiful Hennepin Canal.
100-mile solo | 50-mile solo | 50k solo
Flat and fast, the 50- and 100-mile courses follow the 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 beautiful run, a perfect setting for a PR or first-time finish. Runners are cheered, encouraged and supported by 150 warm-hearted volunteers, many who are ultra runners themselves. At night, the stars above are magnificent.
