The Hennepin Hundred

The Hennepin Hundred is a point-to-point, all-trail ultramarathon organized by Ornery Mule Racing in northwest Illinois. The courses run along the Hennepin Canal State Trail between Sterling and Colona and follow the 104-mile multi-use trail across locks, lift bridges, farmland and small towns.

Race distances offered

  • 100 Mile
  • 100 Mile team relay
  • 50 Mile
  • 50K

Aid stations are located approximately every 3 to 7 miles. The event provides bus service from finish-line parking to the start line for those who need it; the bus service carries a fee of $10.00.

Finishers and participant items vary by distance. 100-mile finishers receive a buckle and a finisher flannel, plus race shirt and bag items; 50-mile and 50K finishers receive shirts, finisher medals, and race bags, with special first-time 50/100/50K shirts noted. Overall awards are given 1st to 3rd for male and female, and artistic age-group awards are presented in 10-year spans.

The race has a 30-hour cut off; finishing within the cut off makes the 100-mile result eligible as a Western States qualifier. Registration often fills and a waitlist is used; waitlist spots are filled in signup order with some guaranteed exceptions for certain Ornery Mule Racing participants.

Refund and rollover rules are noted: no refunds; no-cost rollover if notified by 70 days before the event; 50% event credit available until 25 days before event; other credit and volunteer options are described by the organizer.

Volunteer incentives include credits toward future Ornery Mule Racing events, event swag, and an invitation to a volunteer appreciation event. Visit the organization's website for the most recent information.
