The Bike the Bay route is a 25-mile, non-timed and non-competitive, ride that starts and finishes at Embarcadero Marina Park South located on San Diego Bay.

The 25-mile route follows the Bayshore Bikeway through the cities of San Diego, Coronado, Imperial Beach, Chula Vista, and National City. The ride also features the rare opportunity to pedal across the San Diego-Coronado Bay Bridge! Click here for route information and a map.

Add even more adventure to your Bike the Bay with a little dirt! The San Diego Mountain Biking Association hosts the additional Off Road Option in the Otay Valley Regional Park!  An 8.5-mile loop featuring wide dirt trails, wide gravel dirt roads and a touch of singletrack!  Mostly flat terrain (only less than 300 feet of elevation gain) most suitable for mountain bikes, gravel bikes,  or cross bikes with sturdy knobbed tires. The $10 fee for this optional section benefits the San Diego Mountain Biking Association and their trail work and advocacy efforts for increased access for mountain biking throughout San Diego County.  Click here for the route!
