The Hennepin Hundred

The Hennepin Hundred is a point to point, all trail ultramarathon in northwest Illinois. The course runs along the 104-mile Hennepin Canal State Trail from Sterling on the Rock River toward Colona near the Mississippi. The route follows the canal across historic locks and lift bridges and passes farmland and small towns.

Distances offered:

  • 100 Miler
  • 100 mile team relay
  • 50 Miler
  • 50K

Aid stations are placed every 3 to 7 miles. Bus service transports runners from finish-line areas to the start line; the bus service has a fee of $10. The event cutoff is 30 hours; finishing within that cutoff makes the result eligible as a Western States qualifier.

Early bird pricing is available through January 1 with published entry fees for each distance. Registration closes on September 25. The event has a rollover and credit policy: a no-cost rollover option is available if notified 70 days before the event, and a 50% event credit is available until 25 days before the event. No refunds are offered.

Finishers receive event swag by distance. Examples include a flannel and belt buckle for 100 mile finishers, and shirts, medals, and finisher items for 50 mile and 50K finishers. Aid station captains and volunteers receive registration credits and other volunteer incentives. Visit the organization's website for the most recent information.
