I just hope everyone here can run 5 miles under "controlled" conditions. I'd define controlled conditions as start running, don't stop until you've ran 5 miles, do it in less than an hour, and do it anywhere from 25 degrees to 90 degrees F in shorts, a tshirt, and a hoodie when you want it. I think if you can, you'd be impressed with the ground you can cover in a pinch, not running, but at a slow walk.

I'm sure someone is going to come on here and rant about how my scenario has sneakers in it or something, but isn't that what we're all "equipped" for to have a pair of sneakers, boots, etc, when we need them? I suppose my point is, all the equipment in the world won't help that much if you're in terrible shape.

Disclaimer - I'm in bad shape, but I can run 5 miles.
