This is good fun if you wanna p1ss off some snobby roadies:
I have a reasonable quality, old bike that I use for short commutes, and therefore have it set up for riding in running shoes.
I love causing a stir by wearing my baggiest shorts and t-shirt, and my joggers, then mowing down the regular roadie/tossers on the usual route. We talk about rudeness and hostility; you should see their response when they get dropped by a guy wearing surfing shorts and running shoes, especially when there's 3 of them that can't catch me.

I sometimes hear them screaming at each other to get their drafting organized: "come on, catch the f--ing b@stard"....hee hee hee
(Now
I'm the tosser -- sure glad this is anomynous
