Flat & Fast

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.

Flat and fast, the 50- and 100-mile courses follow 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 perfect course for a PR run, a first 50 or 100, or for chasing a world's fastest time!

Testimonial from Kyle Siefers, first-time 100 finisher in 19:33:28

"Thank you so much for running an excellent race. It was my first 100-mile run and I couldn’t have asked for a better event. All of you truly did a fantastic job and I am so impressed by how hard everyone worked. I saw Michele several times during the race and was constantly wondering if she was just everywhere. I have helped run a triathlon before but nothing of this caliber, so I cannot imagine the stress and commitment it took. Everyone is impressed by the runners, how they are staying up through the night to complete the race, but I know that the race directors were probably up for 72 hours straight. Thank you so much for all of your hard work!

I would also like to thank all of the volunteers. They were amazing, all of them. I loved so many of the stops. Aid 2 had Jello shots, which was awesome (I saw that aid 8/13 had Jack, but I couldn’t bring myself to swallow that at that point in the race). Aid 6 had a great theme going on and made me laugh when they scared me coming out of the tunnel. A special shout-out to Aid 16, who was all alone in the dark but was super friendly and helpful. He was a sight for sore eyes at that point. The fire chief at Aid 20 was just incredible, he had that trial light up like it was the fourth of July and we were thankful for all his awesome helicopter landing lights. There are many others that I would like to mention but will spare you a longer letter. Thank you so much to everyone that helped out. It was a great event and I will be recommending it to other ultra-friends for coming years!
I am donating a small amount to the Trails for Illinois organization as a small thank you gift. Hopefully it helps maintain the Hennepin Canal Trail!

Kyle Siefers"
