The majority of venues have been divided into three zones within Greater London: the Olympic Zone, the River Zone and the Central Zone. In addition to these are those venues that, by necessity, are outside the boundaries of Greater London, such as the Weymouth and Portland National Sailing Academy on the Isle of Portland in Dorset which will host the sailing events, some 125 miles (200 km) southwest of the Olympic Park. The football tournament will be staged at several grounds around the UK.
