See Boulder from the best seat in the world – a bike seat. More info to come!
Boulder offers over 300 miles of bike routes, paths, and lanes. Check out some new views on the B360!
*B-360 is a 24-mile loop that circumnavigates the entire town
*B-180 is about half the distance, a 12-mile route that goes through a few different parts of town.
This free family-friendly ride begins and ends at Valmont Bike Park. The ride will kick off at 10am, however, feel free to start later as the course will be marked.
Stay at Valmont Bike Park after the ride to enjoy free ice cream and local businesses.
Planning on riding the B360 or B180? Sign up ahead of time (link TBD) and avoid the crowd. It also helps us know how many people to expect for bagels before and ice cream after!
**Ebikes welcome: While the City of Boulder urges riders to be mindful of ebike limitations on open space trails, it will not be actively monitoring or enforcing ebike usage during the Circle Boulder by Bicycle (B360/180) event from 10:30-12:30 on June 4, 2023. We encourage all ebike users to power down their bicycles while traversing the South Boulder Creek trail (note: it is downhill) and to cycle safely throughout the length of the ride for the benefit of all those enjoying and sharing the trails during the event.
