Eh? I can barely remember when I finished let alone anyone else. It's a, I'm assuming you're flying 'back' to London. So how are you going to get to the start on the same day? comment. ie. jetlag is hardly an issue if you're not at the start when everyone else leaves...
It starts on the 24th so assuming he's landing in London, it's going to be more than jetlag putting him off the pace :P
