Subject: RE: HR Zones: 220-Age - the TRUTH!This thread has been great reading, so im finally jumping in. I finally did it. 6 months of training using a HRM and using an Avg of different max pred HR for training...I finally went out and did a 30 min TT run. I believe i did it the right way..15 min warmup...10 min at RPE about 7...(HR avg 165) .then last 20 min. RPE.8-10 at the end...Had to back off a little bit with about 9 min to go (side stitch), but after a min, able to rev it up again... Avg HR for last 20 min--176. So--my LT is 176, making Z2 150-160. Ive been using 145-152, so not that far off and was actually probably pretty accurate 5-6 months ago. But my real question is... Should LT be that close to MHR? True, i dont know what my real MHR rate is..calculated is about 184-186 (im 34 and my MRHR is 42), but i've never seen greater than 181 on my HRM. My understanding is that the more fit you get, the higher you can push your LT, but after only 5-6 months of developing a base, this seems a bit high to me. This is kind of a round about way to ask if these numbers seem valid. I hate to focus another 6 months of training using invalid numbers. Any input is appreciated. JT |
