Boris fixed!

final word from the man himself in todays Times.
"As for those gearless bicycles everybody seems to be using nowadays, they are obviously beautiful and ideologically pure, but they are murder to pedal uphill"
so everybody, you aint cool or trendy anymore.

Where exactly on the Cycle Friday ride from Finsbury Park did he have to pedal 'uphill'?

I don't know the route, but I can't imagine there were any real hills ...
