Okay, so I'm a newb to the whole heart zone training thing, but I thought that getting a HRM computer (Garmin 500) and Friel's book Total Heart Training would get me all squared away.
I've had the monitor for a week+ of riding, and have been homing in on my Lactate Threshold by evaluating my perceived effort. I'm about to schedule a metabolic test to confirm things, but let's assume I am correct that I hit my LT at 167 bpm. I've used Joe's LT based charts to enter zones into my Garmin 500, however I'm facing a disconnect when trying to use the MaxHR% data of the 500 to have precise information. Friel's approach is very precise. There is a distinct difference between being at the bottom of a zone versus the top, particular when you venture into Zone 5, which he breaks down in 5a, 5b, and 5c. So using the Zone data of the 500 is precise enough, but using MaxHR% results in this:
How are other Friel afficianados handling this?
Do you just memorize the heart rate boundaries of your zones and use them instead of the percentages the computer provides?
Do you just use the zones and accept not being as precise? The 500 will only handle 5 zones, buy you can set the max to the top of Zone 5a and it will show a "Zone 6" when that is exceeded.
