I've got some of my first ever TTs coming up, so I thought I should try to figure out what my LT HR is.
I just did a test today that I've seen recommended in a few places:
- 15 min warmup
- 30 min TT with the average HR of the last 20 mins being LT HR
My result was 180 BPM, but I did this on the trainer. I tried to push my hardest, but it seems I could have gone slightly harder if I was on the road doing a TT.
I've got heart rate data going back pretty far. Here are some examples of when I felt like I could not push any more:
12 min @ 192 BPM average
1 hr 45 min @ 184 BPM average
5 hr @ 172 BPM average
The first two lead me to believe that today I reached a number that is too low due to being on the trainer.
Those three results are from the road in a competitive atmosphere and the 2nd and 3rd were after a few days of rest.
I'm not looking for an exact number, but I'd like for it to be fairly accurate. It seems somewhere around 185 BPM would be more accurate based on the other data.
Thoughts? Am I doing it wrong?
