Hi How many days are looking to take to complete the journey? If you are an experienced cyclist, you can cover more ground more quickly and therefore require less bookings/money. And do you have a group to ride with already? If you do, then I also recommend arranging your own trip if you want to keep costs down, as it really does not need to cost anywhere near ?1500! A lady I know called Charlie Watson who writes "therunnersbeans" blog did this earlier this year and wrote a couple of good blog entries on it. If you google her website, it should come up. And if you get in touch with her, I'm sure she'd be happy to let you know what they did in terms of accommodation (as don't think all details on that front are covered in her blog). And, if you're up for an even tougher challenge, someone I know runs a London 2 Paris in 24 hours ride in May - PM if you'd like further details! D
