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.

October 6th & 7th, 2018

100 mile solo- 50 mile solo- 50k solo - 100 mile relay

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.

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.

This is the course to set a PR, finish your first 100 mile race, or go for a world record!

Take the opportunity to volunteer at aid stations!
