Reading Eric's recent post on this subject, I am reminded that my runs "are not what they used to be" and I was wondering if The Cool Impossible can help me.
A few facts first: I've been running regularly for about 15 years. The most I've ever run is 10 km and just for the joy of it. Most of the time, I run around 5 km, 3 or 4 times a week [alternate days]. As I am approaching my 75th birthday and just bought "The Cool Impossible", I would really like to do more, more efficiently and more enthusiastically.
I can remember that a year ago I really looked forward to my runs and always finished them with a smile on my face, but not these days. I was running 6 km four times a week with Sprint-8 intervals once a week. But lately, I haven't run 10 km for more than a year and I'm struggling to complete 5 km. Basically, I'm tiring [mainly in the legs] towards the end. Max heart rate rarely exceeds 125. At present, my pace in these runs doesn't even show on the charts shown in The Cool Impossible!
Can anyone suggest where to start? Can I improve my performance? Can I get back to enjoying my runs?
