Debs, I wouldn't like to go by car, at least not the whole way from Frankfurt. The plan is to fly from Cologne to Stansted on Saturday morning (for 45 Euros) and then hopefully getting picked up. I need to talk to Kai as I need them to get my camping gear over and I would like to return with them on Sunday night/Monday morning. That way, I will be back in Frankfurt on Monday afternoon. That's the plan for the 1000 KMs.
For the 24 hours it looks a bit different: The plan is to take Ryan's cattle jet from Frankfurt Hahn to Stansted (47 Euros all inclusive). Then, at Stansted I'll get a rental. That means, however, that I won't see the finish as I will have to leave early to catch the flight back.
