Susan, yee-ha! Think of how much time you've left yourself to train for the full marathon you'll do to celebrate 50! (I, on the other hand... )

Urlea, wear whatever makes you comfortable. Personally I'm small busted but very floppy (even when I was younger) and need a ton of support. If I ran bra-less the bounce would probably wrench my shoulders out of their sockets. Last year someone posted a video some bra company had made about bounce - their findings were that breast size really doesn't correlate with bounce. But yeah... cami, nip-its (or whatever they're called), band-aids, whatever makes you happy! I wish I could go "free!"
