I run, therefore I am

and with a slip of the tongue, there I am.

I was just in a cycle shop, buying a bike carrier for the car. We got chatting - as you do with guys who are passionate about their sport - and one of the salesmen commented that it was unusual for me to have a camelbak when I'd only just got started in MTB. "Oh", I said, "I run."

c'est la vie.
