2012-07-18/22 - London to Champs-Élysées TDF

3 of us are doing this also, heading down from Scotland on the bus, riding from London to Newhaven on the 18th/19th, Dieppe to Louviers 20th,then off to Paris arriving the 21st!
staying the sunday too and getting the eurostar on Monday.

Well up for meeting up to either ride or chill and watch the last stage!

Sounds like you're doing similar to us, we're doing London-Newhaven on the 19th, 23.00 ferry. Definitely up for meeting up in Paris.
