Fun ways to flirt with joggers?

I've been getting into jogging recently and the area I run I see cute or sexy girls running. Many do have earbuds in so I don't bother. But a few don't. I know many don't like to be bothered while exercising but I could be wrong if an opening presents itself. Female joggers or those that workout in general, is this a good idea or should this be avoided and I should continue my run? If it is a good idea, any suggestions? I've never thought to try it but picking up a number while jogging would always be a bonus. Ha ha!

Thanks for the info. I kind of figured this would be the general direction of the answers. I've received a couple of looks and smiles in the past, not often but at least I know. I'll probably just say hi then move on. Let her make the decision.
