About this race
Introducing OconoWattaWoc, a brand-new 5K, & 10K run/walk/ruck on the Interurban Recreation Trail connecting Oconomowoc and Watertown.
Yes, we made up the name. No, we are not apologizing.
The 5K, & 10K are perfect for runners, walkers, ruckers, families, first-timers, seasoned racers, and anyone who enjoys fresh pavement, questionable event names, and the phrase “old trolley line” more than they probably should.
Come run the trail. Walk the trail. Ruck the trail. Pronounce the name however you want.
OconoWattaWoc: Two towns. One trail. Too many syllables.
