Marin County Half Marathon 2020

Race Technical Difficulty Score (RTDS) = 3

Join our U.S. Olympians, awesome musicians, other celebrities and some new friends – as we have ourselves a great day while giving back – all proceeds from the day go back to our community! The Sustainable Sports Foundation donates all proceeds to give as many children as possible from low-income families in our community the opportunity to learn to swim and be safe in the water.

Our family-friendly event (Kids FREE Fun Run starts at 11am) is also environmentally friendly as we strive for zero waste and a carbon neutral footprint. Both the 5K and 10K distances are walker friendly and all three distances boast beautiful views of the bay!
