If you’ve done a traditional 5K, you know they can be a bit lackluster. But the BUBBLE RUN™ is like running through Willy Wonkas’ factory. Clad in white t-shirts, adults, kids and strollers run, walk, dance and play across up to 3 miles of absolute fun! Waves start every 3-5 minutes. Participants will run through the Foam Bogs where there is enough colored foam to cover you from head to toe!
Bubble-teers will also be there to help make sure you get your share of the frothy goodness. Each one of the Foam Bogs is represented by different colored foam. So what if you should accidentally “taste the whimsey?” They don’t taste as great as they are fun, but not to worry. The foam is 100% safe.
Event details and schedule
Please plan on arriving 30-45 minutes prior to your wave start to give yourself plenty of time to park, get your Bubble RUN™ swag, check in if needed, and to get situated.
Please be prompt for your Heat.
Once your heat has started, (the heat is the time you registered for) small waves will be released every 60-90 seconds. Your physical start time is based on a first come-first serve basis, so naturally you will start earlier if you enter the start chute earlier. The last wave within your heat will go out 30 minutes after your scheduled heat (i.e., if your registered heat is for 8AM, the last wave in your heat will leave at 8:30AM).
Bring some extra cash for parking and SWAG!
After you park, bring some extra cash! You'll want to check out our super sweet Bubble RUN store for t-shirts, tutus, and more!
There may be a parking charge of up to $20 for the event that is handled by the venue. With THOUSANDS of smiles present on race day, please have exact change and please don't cut your time too short before the race starts. Cram as many bubblers (legally) into your car to save some cash money money!
The Market Mile is a community-based, one-mile walk/run that invites you to give back and have fun doing it by joining us at our great after-party in Union Station!
Beyond the promise of sunny summer weather, a one-mile course straight down Market Street, the “take it at your own pace” vibes and a buzzing after-party at Union Station, the Market Mile is different because it’s powering up the nonprofits who work tirelessly on the future of our city.
