Both races begin on the black sands of Rodeo Beach before taking runners into the scenic Marin Headlands, up Mt. Tamalpais and through a canopy of redwoods in Muir Woods. While the course is incredibly scenic with ocean views that go on for miles, participants can also expect plenty of climbing and descending with 11,000 feet of elevation gain in the 50-miler and over 6,300 feet in the 50k.

Drew Dinan

Drew Dinan traded the tropics of the Florida Keys for the trails of Bend, OR. Once living the Jimmy Buffett lifestyle, working on fishing boats and owning only a single pair of flip flops, he now has way too many running shoes in his closet and never hears the end of it from his loving wife. He is on a constant quest to find the best happy hours, likes to complain when it’s cold outside, and one day hopes to travel the country writing reviews on chicken wings.
