Hi Andy, and all my fellow newbies.
Unfortunately I can't use my bike to commute, and though I never have and never will be the fittest person around, after nearly a year of very slowly easing myself into getting back on a bike for the first time since I was a kid, I'm really beginning to quite enjoy it. Furthest I've been so far is about 12 miles but I'm pretty happy with that considering how puffed out I was the first time I went out!
