  • 80.5K / 50M — Trail Run


A point to point ultra-marathon race allows runners a chance to pass through many unique towns and countryside. Look for many truss and lift bridges built in the early 1900s for farmers to cross the canal, and the aqueducts that carry the canal and its trail over rivers and creeks. Runners, spectators and crew will want to watch for Bald eagles which are known to nest along the canal, as well as majestic blue herons.

What can you expect of the course? Flat & fast! The surface is about 35% chip-and-seal, almost 60% gravel, single track and grassy lane, and 5% blacktop.

A belt buckle will be given to all 100 miles finishers. Sub 24 hour finishers will receive an exclusive belt buckle.

50 mile, 50k and 100 mile relay entrants will receive a finisher medal.

An artist-made trophy will go to first overall male and female winners. The age group awards: 10-year age spans. .


NEW!!!!! 50k is open to only 100 registrants!

Race Starting line
The race begins in Sterling, Illinois at Sinnissippi Park. 100 mile runners finish at Timbrook field in Colona Illinois. The 50 mile ultra finishes at Lock 17 in Wyanet, Illinois.

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!

Trails for Illinois
We are working with Trails for Illinois to direct a portion of race proceeds directly toward improving this historic trail, as well as growing international attention.
