You will be logging between 2-5 miles depending upon your training level. The link below should give you a relatively clear sense of where we're going. I've also included a verbal description beneath it:
TUESDAY'S RUN COURSE! (this map indicates '6' miles, but we will only be covering '5' miles')
A BRIEF DESCRIPTION OF THE ROUTE-
In short, we will head NORTH from the Marina Green Monkey Bars on along Marina Boulevard until we reach the intersection of Mason/Halleck. This is 1 MILE! Beginners will turn around here and head back to the monkey bars for 2 MILES!
Continue running on the paved path along Mason past SportsBasement. Shortly after we pass SportsBasement, there is a lengthy straight stretch and a funny looking metal power box on your RIGHT. There will also be a 'MM3' in chalk on the ground. This is 1.5 MILES. Intermediate runners will turn around and head back to the monkey bars for 3 MILES!
Advanced and Race level runners will continue past the 1.5 mile mark along the paved path. After roughly 200 meters you will approach the intersection of Mason and Crissy Field Avenue. There is a stop sign and a pedestrian crosswalk here. You will take a quick RIGHT on Crissy Field Avenue and head uphill. Once you've crested the hill you have logged 2 MILES! Advanced level runners will turn around and head back to the monkey bars for 4 MILES!
Race level runners will turn LEFT on Lincoln and continue running towards the Presidio. You'll be looking down at Crissy Field once you're on Lincoln. Enjoy the AWESOME view! Continue running along the sidewalk/shoulder of Lincoln for roughly half a mile until you reach the intersection of Lincoln/Mcdowell. This is 2.5 MILES. I will try to put down a 'MM 5' in chalk on the ground for your reference. Race level runners turn around here and head back to the monkey bars for 5 MILES!
