Hey Ed!
I'm not really sure if that's the case
), but thanks anyway 
.
I went for a 5k TT yesterday(on a 400m track), it was a failure. Plan was to start at 4.05/km and go 5s faster each km till I would reach 3.55/k and mantain for the last 2k. Well, I had to stop after 3k because I was running out of breath... Temp was 15 deg C, so perfect.
Did another TT today on the same 400m track, it was much better, time was 20:10 after 12.5 laps. The watch recorded 5.1km... Calves feel pretty tight now.
Anyway, I wanted to ask you about HR zones.
My current training zones are based on % of HR max which is 191bpm. I had the max of 191 a few months ago, but only once. For example today it was 189bpm. So for the easy runs I try to stay in aerobic Z3(133-153bpm) to keep my HR at around 149bpm(+/-3bpm).
My watch also estimates LTHR, which is currently estimated at 4.27/km @ 171bpm. If I use LTHR to calculate my training zones, then the aerobic Z3 zone is between 152-162bpm.
So, should I switch to LTHR zones calculation method(which will increase the pace for the easy runs), or stay with %HRmax? Which method is better?
