The Hennepin Hundred

The Hennepin Hundred is a premier ultramarathon held in Sterling, Illinois, featuring 100-mile, 50-mile, 50K, and 100-mile team relay races. The point-to-point course follows the scenic, flat, and fast Hennepin Canal State Trail, Illinois’ longest multi-use trail, stretching from the Rock River to the Mississippi River. Runners experience historic locks, lift bridges, farmland, and charming towns, making it ideal for personal records or first-time ultras.

Aid stations are spaced every 3-7 miles, staffed by enthusiastic volunteers. Finishers earn unique swag including flannels, buckles, and medals. The event also serves as a Western States 100 qualifier with a 30-hour cutoff. Visit the organization's website for the most recent information.
