Six miles in and the runners hit Greenwich, where they'll see the magnificent Cutty Sark and the gallant little Gipsy Moth. Some 300,000 visitors come to this maritime centre every year, with an extra 45,000 or so running past on race day. For nonrunners, looking at famous ships is thirsty work and after seeing two of them, the whole family needs a drink, a snack and the loo. This large, efficient pub is right on the spot. There are 150 seats in the garden.
