Three start lines in south-east London merge in Woolwich just before Mile 3. You then pass Cutty Sark, cross Tower Bridge shortly before halfway and loop through Docklands and Canary Wharf. The last five miles follow The Highway, Tower Hill and Victoria Embankment, past Parliament Square and Buckingham Palace, to a finish on The Mall. Water is served from Mile 3, and toilets are at the start, every mile to Mile 24, and the finish. Entry routes include a ballot, charity places and good-for-age.
