For the Chicago people, it’s 18 miles! For those doing Montreal, you can tack on two miles through the Panhandle to get to 20.
NOTE: for those doing 18/20, we plan to start at 7:00 am at the Conservatory of Flowers.
We also have 6- and 8-mile routes for those getting back on track after the SF Marathon.
