Ric,
With due respect, you put it exactly reverse. I was asking for a very general question about an old known method, solely seeking activity-specific spin from fellow cyclists. (Should have known it would be like asking the proper way train by the Friel book on the power forum
)
Honestly, an effort was made to avoid coaxing free coaching out of you all. I respect the talent and effort that go with it.
In retrospect I can see how it's a boring question which would explain the cutting edge, nuanced, posts from so many. It's understandably irritating to answer a neolithic question. So evidently there's no cycling specific nuance to the old method? I'll just go walking at 65%-75% Max HR using 220-age... that was easy.
Please don't take it as a knock to the advice given. As always it is top notch.
Dave
