Here is a link to the course map for 10-13 miles:
Here’s a verbal description for you:
Head NORTH along the Marina towards the Warming Hut. Roughly half a mile in 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.
Head up Long Avenue along the shoulder until you reach a stop sign. This is LINCOLN. Take a right on to the paved cyclist/pedestrian path and follow this path to your right. Stick to this path as it heads 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.
You will follow the path for roughly 1/2-3/4 of a mile. 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.
You will 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 WHO AREN’T PAYING ATTENTION. BE SMART AND BE POLITE IF YOU NEED TO GET AROUND SOMEONE.
Continue to the end of the bridge to the Visitor Center. This is 4.5 MILES. Stop here to grab some water, use the restroom, and/or take a gel, clif shot, etc. Everyone will turn around here and return to the monkey bars.
Upon return to the monkey bars, you will have logged 9 MILES. Continue running SOUTH along the Marina towards Fort Mason Hill by the Marina Safeway. Upon cresting the hill, Beginner runners will turn around here and head back to the monkey bars for 10 MILES.
Everyone else will head down the other side of Fort Mason Hill and head ALL the way to the end of Aquatic Park at the edge of Fisherman’s Wharf. Intermediate level runners turn around here and head back to the monkey bars for 11 MILES.
Advanced and Race level runners will continue into Fisherman’s Wharf. Advanced level runners will turn around at the intersection of Jefferson/Powell head back to the monkey bars for 12 MILES! Race level runners will continue onto the Embarcadero. Run to the intersection of Embarcadero/Bay. Look for the ‘Hillstone’ Restaurant on the right. Turn around here and head back to the monkey bars for 13 MILES!
