About this race

Mt. Tamalpais is the dominating feature in Marin County.  Any true trail runner who sees it wants to run up it.  Here’s your chance.  Our Mt. Tam Trail Run begins at Stinson Beach and climbs (and climbs!) to perched views from Tam before returning via some of the best trails the Headlands have to offer until reaching the beach and bountiful post race food.  Bring the family and enjoy an afternoon with friends in the sand and surf.

Park Information: Mt. Tam State Park, Muir Woods National Monument
