Celebrate Walk and Bike Month by walking ALL the way around Boulder on the 26-mile Walk 360 Slow Marathon!
Join a grand all-day adventure, walking counter-clockwise all the way around Boulder! We’ll traverse every kind of walking surface in the city, explore diverse neighborhoods and enjoy cool parks and open spaces along Boulder’s urban edges. The Walk 360 gives Boulder walkers a whole new perspective on the city, demonstrating people-friendly connections among destinations and safe ways to get around Boulder’s busiest streets by foot. We’ll have plenty of places to stop for breaks and water along the way, and we’ll take a lunch break in South Boulder.
Registration is required and is free. Everyone who completes the route will receive a Walk 360 sticker. Challenge yourself to this one-of-a-kind adventure!
Schedule and Planning: We’ll meet at Four Mile Canyon Creek Trailhead at 7:00 a.m. and finish the full loop by 6:00 p.m. We’ll walk counter-clockwise, going from Lee Hill Drive to North Boulder Park, on to Chautauqua, South Boulder Recreation Center, East Boulder Recreation Center, Valmont Bike Park, and back to the starting place. Be sure to drink plenty of water on the days leading up to the event, and use the restroom before showing up at Four Mile Canyon Creek, as there are no facilities on site.
New for 2025: Earn Limited Edition Collectibles
Walk and Bike Month brings something new every year—fresh events, fun routes, and great giveaways for walkers and riders of all ages and abilities. This year, we’re excited to introduce something special: limited-edition collectible brag tags for four walking events.
How Can I Get a Brag Tag?
You can earn them by taking part in select Walk and Bike Month events and activities throughout June. Each event you attend gives you the chance to collect one new piece—so the more you participate, the closer you get to completing the set. Whether you’re walking, riding, or doing both, it’s a fun way to celebrate your movement and show off your accomplishments.
Tags are up for grabs at these event—but there’s only a limited number, so be sure to swing by early and snag yours before they’re gone!
- W180 East or West: Walk 12.4 miles around Boulder on May 24 or June 7 to earn this tag.
- Big Boulder Dog Walk: Join the fun with your pup on June 14 to grab the second tag.
- Walk to Work Day: Stop by the Bike and Walk to Work Day Happy Hour on June 25 for this tag.
- W360: Slow Marathon: Complete the W360 on June 28 – or complete both of the W180 walks – to claim the final tag.
