london to cardiff via bike
I'm in London now from Aus with my touring bike. I had bike plans but they've all been thrown into disarray, namely by it being far too cold to camp as I'd planned. At the moment I want to get to a friend in Cardiff or Swansea from London. I've got about a week and I'd like to ride there. I don't have the internet time or resources here to research this properly so hopefully you guys can help me out - is there a cycle route out of London (i think I remember something about along the Thames)? What would be a good way to get to my destination. This will be my first ride so my fitness is low and I'll have about 6 days to get there - doable?
