I'm 47 years, woefully out of shape (about 5'8" and 200 lbs)and more than two decades past my so-called prime. But I want to get somewhat serious about running again, and I'm wondering what my realistic expectations should be. A little background:
My aproximate PR's - most set about 22 years ago - are as follows: 1500 (4:00), 5K (15:00) and 10K (32:00).
Presuming I could lose 50 pounds and work back up to a meager 40-45 mpw, will it be possible to sub-6 pace for a 10K again? Or will my years of relative inactivity and carrying extra weight make it physiologically impossible to run that...uh..."fast" again?
