The The Hennepin Hundred is a 50k, 100 miles, relay, and ultra event held on Saturday, October 3, 2026. It is located at Sinnissippi Park Road in Sterling, Illinois.
Join us for the 9th Annual Tiger 10 Miler Trail Race presented by Byron Bank! This exciting race will take runners on ten miles of twists, turns, and hills within the Byron Forest Preserve and the more secluded Nardi Equine Prairie. All participants will receive a custom finisher's medal, shirt and our unique age group awards go 3 deep in 5-year brackets. Overall male & female winners and also male and female masters winners will receive awards and a cash prize. Special awards will be given to five year finishers of the Tiger 10 Miler. Those five years don't have to be consecutive, just five total finishes. This is a "cup free" race so please bring your handheld water bottle or hydration pack as we won't have paper cups at our three aid stations in order to keep our trails clean and be environmentally friendly. Following the race, the after party will be held at Hairy Cow Brewing Company from 10:00 a.m. to noon. Race participants will kick back and enjoy complementary pizza while
awards, cash prizes, and door prizes are distributed! "Like" or "follow" us on the socials @Tiger10Miler for updates and pictures of the course.
