Someday they won't even look dorky to you.
Really, I can't imagine riding in regular shorts. Even on my 8+ mile commute I suit up.
I've done it in tennis shorts, but it sure feels better in bike clothes.

One thing: Skip shorts. Just man up right now, admit you cycle and spring for bibs. Really.. Seems weird, but if you're out over an hour you'll be happy you did.
