B360 - Circle Boulder by Bicycle
Coordinated in partnership with Community Cycles, the B360 Circle Boulder by Bicycle Ride is part of Walk and Bike Month, a signature community event designed to support the city's sustainability and Transportation Master Plan goals. Visit walkandbikemonth.org to view a complete list of Walk and Bike Month events going on around Boulder.
This year we aren't able to host the B360 Circle Boulder By Bicycle Ride and celebration, but you can still do this ride alone or with family members this summer by following our route map below.
The leisurely, 22-mile B360 and 11-mile B180 self-guided rides 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.
The interactive map below displays the routes.

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.
