OK...I've done some searching and I saw a similar thread posted a few months back with a "don't worry too much" set of answers...but I feel I ought to follow up a bit because I think my own situation is just...weird.
OK...first of all, yes, I know I'm in pathetic shape and that is probably the answer to this...but...
Vitals:
38, male, no regular exercise for quite some time, overweight (190...I'm aiming for 165).
I decided to try easing into running again last week and found it a bit easier than I thought (especially compared to recent attempts - see my "atypical newbie" thread). In short what I've run so far is:
4/6: ~1.5mi
4/9: ~ 1.66mi
4/12: 5k
4/14: 5k
Here's the catch. Before tonight's run, I picked up a heart monitor. At 38, the standard (yes, I know this can vary substantially) is MHR = 182, so the HM (Polar) wanted me to stay 115-155.
OK, so on my warmup walk I'm already into the 120s.
After warming up I start my current very slow jog (~ 13 minute pace or so) and it doesn't take long before it's cussing at me for busting 155. I'm hitting high 150s and low 160s in an easy jog. Not breathing hard - I could still be converstational without much difficulty. Nevertheless, I figure I'll try backing down a bit. Eventually (after about 2 reps) I got too frustrated at walking half and jogging half a lap...so I just kept jogging and stayed at 158-160.
Got to my last (450m) lap and was feeling pretty good so I kicked it up a notch and ran the last ~ 1.1 laps at a ~ 10 minute pace. This got my breathing into overdrive - depe breaths, 2 paces in, 2 paces out and my heart hit 181 on that lap. I backed off a bit at the end and crossed the line at 170.
Heart rate recoveyr was pretty good - I dropped 40 beats in the first minute.
Almost sounds to me like I'm aerobically OK, just don't have the "support plumbing" for running - when I have been exercising I've done more on exercise bikes than running. The 9 miles I've run in the past 8 days represents more running than I've done in 17 years.
Also, from about 1/4mi into the run up until...oh...1/4 my calves get pretty uncomfortable/stiff....but eventually it passes and the last mile or so was pretty much coasting for me (hence the final lap boost).
Should I do anything different or just keep running 2-3 miles at a crack until my muscle plumbing builds up...or....?
