Grilling-specialist Jeremy Paxman is a neo-cyclist: "It is easily the quickest way around central London, faster than bus, Tube or taxi.

It does not clog up the streets."

Fashion designers Jeff Banks and Paul Smith are avid roadies. Smith’s company has sponsored cycle teams, and Banks Jnr owes his love of cycling to Banks Snr: "My dad was a racer before the war. He bought me an Italian racing bike when I was 11, and I suppose I’ve never looked back. There’s not a major col in the Alps or Pyrenees that I haven’t climbed. I suppose I do it for the sense of achievement you get when you complete rides like that. It’s amazing."

Failed US president candidate John Kerry is a mad keen road cyclist, owning a custom-painted £3000 Serotta Ottrott which he pedals when he gets a spare moment on the campaign trail.

He said: "Nothing compares to getting your heart rate up to 170-something, riding hard for an hour-twenty, getting off and not hurting, as opposed to 24 minutes of running, at the end of which I hurt. When you ride a bike and you get your heart rate up and you’re out, after 30 or 40 minutes your mind tends to expand; it tends to relax."
Shadow Secretary of State for the Regions, Bernard Jenkin drives to his London home on Sunday evening and then doesn’t touch his car for a week: "I cycle everywhere, every day – to Westminster, to meetings in the West End and the City, to the Albert Hall, to the Royal Opera House.

Writer Beatrix Campbell is a confirmed cyclist: "In the context of the great debates about identity politics – are you gay or straight, nationalist or republican, British or English and so on – I would ask, "Do you ride a bike?".

My contract actually offers me a free car from my home to my office and back, but I suppose I am addicted to cycling."
