You will be logging between 2-5 miles depending upon your training level. Here's a link to the course map for your reference-
Tuesday's Golden Gate Park Run
Everyone will launch from the paved path to the RIGHT of the ballfield. You will follow this path behind the ballfield(s) and turn RIGHT onto Middle Drive East.
You will follow Middle Drive East towards John F. Kennedy Drive (the main drag in Golden Gate Park). Once you reach the intersection of Middle Drive East and JFK, you will cross over to the RIGHT side of JFK via the pedestrian crosswalk and turn LEFT on JFK.
From here, the rest of the run is pretty straightforward. Follow JFK past the intersection of JFK/8th Ave. Just past this intersection, there is a pedestrian crossing on your LEFT that is adjacent to Hagiwara Tea Garden Drive. I will put down some chalk markings indicating 'MM 1' signifying the 1 mile mark. BEGINNER runners will turn around here and head back to the ballfield for a total of 2 MILES!
Everyone else will continue running along JFK into Golden Gate Park. Eventually you will pass the Stow Lake Pavilion which is on the LEFT off of Stow Lake Drive. Once you pass Stow Lake Drive you will see a YELLOW sign indicating '13'0 Clearance'. Look for a chalk marking on the path indicating 'MM 1.5'. INTERMEDIATE runners will turn around here and head back to the ballfield for a total of 3 MILES!
Advanced and Race level runners will continue running along JFK underneath the overpass and through the intersection of JFK/Transverse. At this intersection there is a water fountain if you need it. Shortly after you run through this intersection, you will pass 'Lloyd Lake' on your RIGHT. Just past this lake you will see a sign/banner for 'SF Rec & Park'. Look for a chalk marking indicating 'MM 2' on the path. ADVANCED runners will turn around here and head back to the ballfield for a total of 4 MILES!
Race level runners will continue running for another half mile until they approach Lake Spreckles on the RIGHT. As you approach Lake Spreckles, look for a chalk marking indicating 'MM 2.5' on the path. RACE level runners will turn around here and head back to the ballfield for a total of 5 MILES!
