On the wider point though... late last century when I was fit and had a full head of hair... I would ride my bike to the station at Camberley and take it to London, then ride to never-became-Mrs-Morat's place in Earl's Court. People thought I was mad to ride in London and it was, truthfully, genuinely scary in places. Back thenI was used to cycling in Liverpool which was scary for other reasons. ie "ey Mate, givvus a go on yer bike?"
