I'm still hanging in at a much more 'leisurely' pace, if you can call running 'leisurely'.... he he he 
I'm too freaked out by any knee pains as I know what the impact can be. The original injury took about three years before I didn't have severe pain hiking down hills. So... I'm mostly lurking here and just slowing the program waaaaay down. Any pain and I stop. But today, NO PAIN!!! Yahoo! I ran 5/5/5/10 for a total of 25 minutes. And right now I'm feeling the endorphins, oh yeah!
My muscles, ligaments, tendons, flab, etc. are slowly becoming accustomed to the movement. If you had asked me weeks ago, I would've told you that my limiting factor would be the pounding heart or my screaming lungs, but nope, those are working fine! Which is exciting for me.
By the way, I personally think Tracy is more than a 'little crazy' but she sure looks fantastic in her current photos! And besides, who knows what the impact of exercising 5-6 hours a day on 1200 calories is on the mind? I'd probably be more than a 'little crazy' too
