Big Battlefield Bike ride

Well I've been accepted for a place on the Big Battle Field Bike ride, essentially it's a ride from Portsmouth, over on the ferry to France then we cycle towards Calais visiting various WW1 & WW2 battlefields along the way for around 350 mile then get the ferry back to Dover then do a big ride round London.
I'm really looking forward to it as it's something I would never normally do and it's an amazing opportunity. I've got to raise £2000 for it which is probably going to be the hardest part.
