We've done this run several times and it's always a blast!
Come run 14 miles with us starting at the Ferry Building (we'll meet under the clock tower), run along the Embarcadero, past the bridge, out on the trails to Land's End (the best part!) along Great Highway and back. Brunch, of course, to follow :)
Below is a map of the course. Looks like I might have incorporated some hills which we can decide on the run whether or not we'd like to take them on.
