I'm not planning on competing in marathons any time soon, but my 11 year old has started running for basketball conditioning, and I thought I'd try to go with him. My problem is my chest. Without the proper bra, running is downright painful. I have a good, supportive sports bra, but it's not enough. So my first question is this - how do I keep the girls largely immobile? Does anyone use two for extra support? (Wrap 'em up in Saran Wrap or something? ).

I'd be looking at 5K range at most. He's only running a mile right now. Is this even do-able? Is there anything technique related that might help me (kinda doubting it, as you can't do much about gravity)?

Thanks!
