Discovery Bay Community Foundation hosts the Discovery Bay Tri
Nestled in the shadows of Mt Diablo where over 13, 000 residents live & play, you'll find Discovery Bay. Our courses are built for the novice and advanced athlete alike. Music, lunch, great prizes, athlete goodie bags, a boat cruise? All part of the inaugural Discovery Bay Triathlon. Come on out and discover a new race you'll want to return to year after year.
