About The Golden Gate Headlands Marathon

The Golden Gate Headlands Half Marathon in Mill Valley, California is a breathtaking race that takes runners from the start line at Rodeo Beach to the finish line in downtown Mill Valley. The 13.1-mile course winds its way through Marin County’s stunningly beautiful landscape, with sweeping views of San Francisco Bay and majestic Mount Tamalpais looming overhead.

Runners will begin their journey on the flat terrain of Rodeo Beach before heading up into the hills above Sausalito, where they can take in panoramic views of Golden Gate Bridge and Angel Island as they ascend towards Muir Woods National Monument. As they reach higher ground, runners will experience a mix of rolling hills and challenging climbs as they make their way north towards downtown Mill Valley. Along the way there are plenty of opportunities to snap some Instagram-worthy photos against a backdrop of lush forests, tranquil creekside trails, and serene waterfalls!

The typical weather for this time of year is mild but unpredictable – be sure to bring layers just in case it gets chilly. Although snowfall is rare during March in California’s foggy coastal climate, you may experience windy conditions or an occasional sprinkle throughout your run; so be prepared! Despite these potential obstacles however, most agree that this race offers some truly unforgettable scenery that more than makes up for any inclement weather you might encounter along the way.

The half marathon attracts crowds primarily comprised by local running enthusiasts who come out to cheer on fellow competitors while enjoying all that Marin County has to offer – making it one big celebration! There’s always lots of energy around every corner which helps keep spirits high amongst both participants and spectators alike – ensuring everyone has an enjoyable experience regardless if they’re competing or just there showing support!
