Excellent point. Most important thing is to get out there and RIDE. Build base miles. A lot of 'em.
There's nothing more despicable than some chunky out-of-shape dude puffing away on a climb on a brand new $5,000 carbon fiber/TI bike with Campy Record or full Dura-Ace stuff on it. Oh, and a "Discovery team" jersey.
Yep, they're out there.
I enjoy cooking such guys on my 20-year-old frame with mismatched parts and my "DRINK MORE BEER" jersey. And I'm not even that good.
