Now in its 14th year, the Marin County Triathlon is continuing its tradition of being one of the world’s most environmentally conscious triathlons.
The Olympic distance event offers a refreshing 1.5K swim in San Pablo Bay; followed by a challenging 22-mile bike course through China Camp State Park; concluded by a 10K out and back run course along the waters of San Pablo Bay.
The Sprint distance is a 500-meter swim, 8-mile bike, and 5k run.
Each year we offer our Duathlon series in addition to both Sprint and Olympic distance triathlon races. This run, bike, run event is a one-mile run to start the Sprint and a 5k run beginning the Olympic in lieu of the swim, then joining the triathlon bike and run courses for their respective distances.
With the courses’ connection to the natural landscape and commitment to sustainability, the Marin County Triathlon events are magnificently scenic, spectator-friendly and gentle on the environment.
We hope you will join us for this year’s races, either as a participant, volunteer or sponsor.
