Take on the hills of the Garin Park XC Challenge in one of the beloved East Bay Regional Parks. Complete with stunning views, challenging climbs, and a few gopher holes to keep your wits alive, this ~5k XC race will make your quads burn like the ends of a beef brisket, and your lungs rethink their purpose in life. After your heart consults Webster's to make sure it does indeed have the correct definition of myocardial infarction, it will bask in the glory of a flat ~0.5 mile stretch into the finish where it feels all the love.
A staple on the USATF Pacific Association (PA) Cross Country Grand Prix, this event is finally old enough to have a beer (legally)!
Come join in the fun!
