The City of Boulder/GO Boulder Transportation Division will host the 22nd annual Circle Boulder by Bicycle community ride in June 2020. Stay tuned for more details.
The leisurely, B360 and B180 self-guided rides will explore the city's extensive bike system of multi-use paths, protected bicycle lanes, buffered bike lanes and on-street bike lanes throughout the city and then return to Valmont Bike Park for a FREE, post-ride party with refreshments. The FREE, non-competitive bike ride is open to all ages and abilities and will take place rain or shine.

The B360 and B180 Bike Route
The B360 and B180 routes use the community's bike system of connected paths, neighborhood streets and unpaved trails. Riders can register for free on the day of the event at the Valmont Bike Park and then begin riding by yourself or with a group of friends.
The B360 is a 22-mile bike route and riders are encouraged to begin in small groups between 10:30 and 11 a.m.
Riders who want to bike the 11-mile B180 bike route can begin riding in small groups between 10:45 and 11:15 a.m.
Both the B360 and B180 routes are designated to be ridden clock-wise and start and end at the Valmont Bike Park.

Walk 26 miles all the way around Boulder throughout Walk and Bike Month with Boulder Walks! We will walk the first four Sundays in June, from 8 am to about 11 am, finishing each walk at or near places to enjoy lunch together. Walk the route at your own pace, or join us as we walk the full 26-mile loop in one Slow Marathon day! Along the way, we'll explore Boulder history and innovation, learn about the city's work to integrate more walkable and transit-accessible places into every neighborhood, and enjoy getting our steps in together. Bus tickets will be provided to help you get back to our starting places on the segment days; carpooling is also encouraged. Visit Boulder Walks for more information on all the walks going on around Boulder and also visit walkandbikemonth.org for all the special June Walk and Bike month events.

Five Rules of the Road to prepare you for safe and fun bicycling no matter where you're riding:
FOLLOW THE LAW
Your safety and image of bicyclists depend on you. You have the same rights and responsibilities as drivers. Obey traffic signals and stop signs. Ride with traffic; use the rightmost lane headed in the direction you are going.
Make your intentions clear to everyone on the road. Ride in a straight line and don’t swerve between parked cars. Signal turns, and check behind you well before turning or changing lanes.
Ride where people can see you and wear bright clothing. Use a front white light, red rear light and reflectors when visibility is poor. Make eye contact with others and don’t ride on sidewalks.
Anticipate what drivers, pedestrians, and other people on bikes will do next. Watch for turning vehicles and ride outside the door zone of parked cars. Look out for debris, potholes, and other road hazards. Cross railroad tracks at right angles.
Check that your tires are sufficiently inflated, brakes are working, chain runs smoothly, and quick release levers are closed. Carry tools and supplies that are appropriate for your ride. Wear a helmet.
