I was diagnosed with cancer last year and have undergone a lot of chemo and a major surgery since then. I want to try to start to make a come back but my body just isn't quite what it was...in many ways. Has anyone had a serious set back like this and at least gotten back into it? I'm an old 15 flat 5k guy and if I "ran" three miles at 90% max heart rate right now I might break 45 minutes. And, that would nearly destroy me. I hardly feel like there's any point in my mid-30's to try and get back under 30 or 25 or 20 for 5k. I know it sounds insane to even my old self to call 15 minute pace running. But, I wish I could just go out and run. Forget racing and "training". I'd be happy for a jog. Just trying to see if I should officially black list letsrun on my router and pray I never see a jogger again.
