Kittredge Park → Columbine → Private Kittredge Land → O’Fallon → Back to the Park

Join us for a one-of-a-kind community trail race through the heart of Kittredge. This 7.4-mile route starts at Kittredge Park, runs down Columbine, crosses through a special stretch of private Kittredge property, winds through the beautiful canyon trails of O’Fallon, and loops back to finish where we started.

It’s challenging enough to earn it but inclusive enough for everyone to take part.

Runners and hikers are both welcome (hikers will begin shortly after the runners). Whether you’re pushing the pace or soaking in the scenery, you’ll be part of something meaningful.

Please note: Hikers should be comfortable maintaining a steady 20-minute mile pace so we can wrap up together by 11:15 am.

And when you cross the finish line?

Stick around. We’re turning Kittredge Park into a post-race hangout with food, drinks, music, and a fun kids run to wrap it up. Kids and dogs are welcome. Bring the whole crew.

What's included in the adult ticket price: trail hat, running club support leading up to the race, lunch, post-race rehydration and snacks, post run sauna and cold plunge in bear creek, local discounts and other day-of perks, and a donation to the flashing crosswalk signs.

What's included in the kid ticket price: run their age in laps around kittredge park, snacks, prizes, and a donation to the flashing crosswalk signs.

RUN CLUB DATES (meet at Kittredge Park at 9 AM): Sunday, March 29th | Sunday, April 12th | Sunday, April 26th

Local trails. Local businesses. Local impact.

Let’s run for something bigger than ourselves.
