Enjoy the beauty of the Bay by bicycle!

Bike 4 Breath is more than just a cycling event. It's a day full of fun where riders of all levels come together to support clean air and healthy lungs.  Cyclists raise funds for asthma education, lung disease research, and clean air advocacy in support of the work of Breathe California Golden Gate Health Partnership and Breathe California of the Bay Area. Read more about our organizations and our work here.

For over 20 years, Bike 4 Breath has brought together hundreds of cyclists.  This year, Bike 4 Breath will start and end at Coyote Point Park in San Mateo. Route options include a family friendly 10 mile route, a 30 mile intermediate route, and a challenging 65 mile route for the serious cyclist. View our event details for the full scoop!
