Saturday's Course Map
Here's a verbal description as well:
Everyone will head NORTH along the Marina towards the Warming Hut.
Roughly half a mile into our run (near Baker Street) we will make a RIGHT TURN and cross through the volleyball court area into the Yacht Club parking lot and TURN LEFT onto the Marina Promenade. This is a gravel/dirt path that heads towards the Warming Hut.
Upon reaching the Warming Hut (roughly 2 miles), you will run past the Warming Hut and take an IMMEDIATE left to head towards LONG AVENUE. Long Avenue is effectively a short hill that heads up towards Lincoln. Crest the hill and turn RIGHT onto the paved pedestrian/cyclist path. Eventually you'll see a parking lot to the LEFT. Look for a 'MM5' in chalk. Beginners will turn around here and head back to the monkey bars for 5 MILES!
Everyone else will continue following the pedestrian path towards the Golden Gate Bridge. Make sure that you are on this path and NOT on Lincoln. You
do not want to be running on Lincoln for this course. There will be a few
points at which the path may fork, but stick to the MAIN path. You will
soon see the Golden Gate Bridge approaching.
reach a point where you can continue running and run underneath the
bridge or take a hairpin LEFT and wind your way up to the pedestrian
side of the bridge. You want to do the LATTER and turn left and head onto the pedestrian side of the bridge.
PLEASE BE CAREFUL! THERE ARE TYPICALLY A REASONABLE NUMBER OF
TOURISTS AND CYCLISTS WHO AREN'T PAYING ATTENTION. BE SMART AND BE
POLITE IF YOU NEED TO GET AROUND SOMEONE. STAY ON THE 'RIGHT' SIDE OF
THE BRIDGE ON THE WAY OUT AND THE 'LEFT' SIDE ON THE WAY BACK.
Shortly after getting onto the bridge you will see a 'MM6' in chalk on the bridge. Intermediate runners will turn around here and head back to the monkey bars for 6 MILES!
Advanced and Race level runners will continue running along the pedestrian side of the bridge. A half a mile later, you will see 'MM7' in chalk on the bridge. Advanced runners will turn around here and head back to the monkey bars for 7 MILES!
Race level runners will run for another half a mile until you reach the second tier/pillar of the Golden Gate Bridge. You will turn around here and head back to the monkey bars for 8 MILES!
