Since I have signed up to do a half marathon this fall though, I figured I need to get out and start running outdoors, too, now that spring is making an appearance. And man does it kick my bum! I find myself struggling to run straight through for 5-10 min at a stretch. Should I be watching to do things any certain way, or is there really that big of a difference between treadmill running and outdoor running? Am sure a month from now the latter will be much easier, I'm just a bit surprised at the difference! Has anyone else experienced the same problem?
