Flew into London on WOW airlines. Not recommended though I have to say they handled the bikes without any hassle and they made it in one piece. After 24 hours without sleep we managed to get the bikes together in 20 min at Gatwick airport and took a Thameslink train into London. 

In the morning, we jumped on a train to Edinburgh. Virgin trains have space for a few bikes in the luggage car, though you should make a reservation for them when you buy your tickets. 

We will spend a few days in Edinburgh sightseeing and getting ready for the ride.
