I admit, I've been skimming the responses, but has anyone said:

sore bottom? I hear that ALOT. They ride once and their bum hurts. So they never do it again.

And the bike jerseys/kits are UGLY (not my opinion, but I hear that alot).

And who wants to wear spandex shorts, OMG! Especially if a guy will be riding a foot behind you!!!!

I will never forget the first time I rode with DH and he told me my bum jiggled a lot. It's a good thing I'm not overly sensitive.
