At age 64 I am running 40 kms a week, comprising 4 x 10 kms. On my rest days I usually cycle around 10 kms each day. Up until year 2000 I was runnning 7 minute miles as my normal pace for any distance that I ran,up to 15 miles, never having ran farther than that. Then I had a medical problem, ( prostate. ) and had to stop running for almost a year. I am now almost 2 years back into my favourite pastime, but cannot, without tremendous effort, get better than 9 minute miles,and then I have to stop and walk for a couple of hundred yards every 2 miles or so. I have used the walk / run routine and can manage some fairly good speeds for a hundered yards or so, and then slow jog again. My problem is shortage of breath, I just cannot seem to get sufficient air into my lungs to sustain the required effort to attain 7 minute / mile pace. Is this purely down to my age now, or is there some way in which I can improve my lung capacity ? Incidentally, I am also, at 85 kilos,about 10 kilos heavier than I was before my enforced lay-off. Is this the cause??
Any responses will be appreciated.
