After getting the news two days ago that my heart checked out superb after having a massive MI a couple of months earlier, that indeed there appeared to be no damage (Although that has yet to be confirmed with further testing) I guess I got pumped up. I managed, on a treadmill, to beat my old record on a mile of 5:27 by a few seconds. I’m still overweight for a serious runner, jogging/running this hard is very new to me (The upside? I have no impact issues). I weigh just over 160 and that’s at only 5’8″, but I think there’s potential. I have a big set of lungs and the doc says as hearts go, mine is large — not enlarged, just big for someone my size. Plus I’m certain I can lose another 20 – 25 lbs by early to midsummer.
Assuming everything tests out OK in my next follow up in 60 days … my question for the runners among you: how realistic would it be to train to break 5 minutes and if that’s even in the realm of possibility, what would be the safest or smartest way to go about doing that? Right now my heart rate is great even at the end of that kind of run, it barely goes above 160 (I have to do a hands and feet elliptical at high levels for about 5 mins to exceed 180 bpm). To put this in context, a five minute mile means running 12 miles an hour on average. I can barely hit and sustain 12 MPH in an all out sprint for 30 seconds.
What’s giving out are my legs, quads mostly, and a little bit in my calves. And I do mean giving out, at the end of that last best mile my quads were beyond burning and had reached a state of almost complete numbness, barely able to respond, I was on the verge of staggering off the treadmill because the muscles were so toasted.
