Jogging: "Everybody's Doing It"

So I'm trying to become a jogger. (Everytime I talk about jogging, I can't help but think of Anchorman when Ron Burgandy says,

"Veronica and I are trying this new fad called uh, jogging.  I believe it's jogging-- or yogging.  It might be a soft j.  I'm not sure, but apparently you just run for an extended period of time.  It's supposed to be wild."

I love that movie.)

One of my dearest friends has become a bonafide runner, and I'm trying to get it together enough to do a 5K race with her in September.  5k should be no big deal, right?  I am in reasonably good shape, after all.  But so far I just feel pathetic, as it feels like someone is stabbing me in the hips and sooner, rather than later, I'm just limping along.  (I think this is because of my bowed legs.)

However I've got some new stretches, and a whole 5K plan, and G to cheer me on.  (He's totally joined The Jogging Craze.)

Any tips?  I mean, besides wearing outfits like the ones above?
