That's awesome; congrats!
I've been doing more at the gym for strength training since my doctor visit a month ago, but I've been really slow to actually pound pavement again. I tried it out for the first time in weeks a few days ago and couldn't make it two miles - my lungs lost all acclimation to running in sub-freezing temperatures. But I managed to do three miles on the treadmill a couple days later without any major problems, so I'm encouraged. I finally bought a foam roller too, and am going to start working that into my conditioning since so many runners I know have sworn by it.
I really want to go running today, since I'm bored to tears and restless - but it's still sub-freezing (WTF, spring?), and my knees aren't feeling 100% - don't want to risk reversing the progress I've been making. Aaaaaaaargh.
