Thanks a lot, EZC, very helpful stuff.
I do have one question, and it might be a dumb one but I'll ask anyway...You mention logging distances, but what's the best way to tell exactly how far you've run? Will a simple pedometer do the trick, or is there a better piece of technology? Or do you usually estimate it? I'm one of those numbers guys, and one reason I like treadmills is because I can tell the difference between running 3.00 miles and 3.20 miles...but I'd like to be able to do the same thing in the outdoors.
By the way, it seems from your handle that you live in Boston. Have you qualified for the Boston Marathon there yet?
