Getting wild in a city near you...

A long time Bay Area favorite park with so much diversity you will want to come back for more! Plenty of single track and fire roads (along with some serious elevation) presents an exciting challenge for all levels of runners. Everywhere you look gives you a unique perspective of the Berkeley hills and San Francisco Bay along with plenty of wildlife throughout the courses. Come join us and be a part of this event at a Bay Area gem hidden right around the corner from everyone in the Bay Area.
