K Pax-ian running

[Mid Life Crisis Marathon Man]

Hi RB - I've given up trying to work within the zones, although I do still take a mild interest afterwards in how long I spent in each zone, but it's not something that is particularly useful at my current level of running.

I use a max HR (183) calculated by the HRM, and I'd say it was fairly much correct because once I get over the 95% mark I have the insatiable urge to buy more life insurance

But anyway I'm glad you call 80% aerobic, because I have to agree that I think that's the case too - certainly I can run reasonably comfortably at that level, which suggests it's primarily aerobic.

What I really like about the HRM is that it gives me another means of verifying my progress without having to use the stopwatch. So I can go for a long slow run, and compare my heart rate with previous slow runs instead of being forced to try and run faster all the time in order to measure progress. If you multiply your average HR for a run by the pace per kilometre/mile, you get a crude, but handy little performance index of the run, and can actually compare any two runs that way. But I'm really getting into number madness teritory now. I must start going to Stats Anonymous meetings again... at the moment I'm averaging less than 1.23 meetings per month, and then I'm only staying for 67% of the meetings total duration...
