Five of the torchbearers who will carry the Olympic flame, joined gold medal-winning triple jumper Jonathan Edwards and London Mayor Boris Johnson at a primary school in east London to mark the detailed route of the torch relay being released.
Steven Tomlinson, the teenage son of cancer sufferer and fundraiser Jane Tomlinson is from among local people, chosen to be torchbearers. He said he was proud to be doing this.
Diana Gould the oldest torchbearer aged 99 said she was very excited.
London mayor Boris Johnson said the torch was going throughout all the boroughs of London.
8,000 people will carry the flame on its 8,000 mile journey. And each torchbearer will carry the flame for about 300m. It will visit every nation and region and stop off at landmarks such as Stonehenge and the Giant's Causeway.
The Olympic flame arrives in the UK on 18 May and begins its 70-day journey at Land's End on the morning of 19 May.
