The Olympic flame will trek about 8,000 miles but almost entirely on British soil during 70 days next summer, according to the article.
Additional details are available at the official site for the Olympic Torch Relay. Of course, part of the Torch tradition will also take place in Olympia, Greece.
The destination list for the flame looks good to me. It would really be something to see the flame at Stonehenge, for instance.
I did not yet look closely at the route yet, but in case they did not think of it already, consider this my Olympic blogger suggestion that the London 2012 Olympic Torch Relay Team at LOCOG, as well as Coca-Cola, Lloyds TSB and Samsung, recreate the "Chariots of Fire" opening sequence by carrying the Olympic torch down the beach made famous by the film's director, Hugh Hudson, and Vangelis (in case you missed it, Hudson answered questions about that famous scene during a film festival in Atlanta, and his comments are available via this post).
