It is the classic of the classics. Most of it on cobblestones. And they ride it on skinny tyres!
I've got a few videos via Diario de un Biciorejón which I find tiring just to look at.
Since it is actually not too far from the UK (near Lille), we are planning on watching it live next year. We will ride to Dover and then ferry over to Calais, and onwards to Lille. Should be good fun. Any takers?!
