How do people approximately calculate their LT1 and LT 2 without a blood test?

What are you doing to get estimates on your 530? I have a 1030 and have not received any LTHR estimates.

wear a chest strap that supports HRV (Garmin dual HTM) power meter on bike set 530 to auto calculate FTP record all rides on 530 When the 530 provides an FTP estimate, it also provides LTHR estimate. On the same screen.

I’ll have to check my settings tomorrow. I record all my rides on either my fenix 6 or edge 1030. Maybe I should pick one and stick with it. I always wear a heart rate monitor and always record my power. :man_shrugging:

week and a half ago, after some zone5 (315-320W): [image] and tonight, after couple 10-min threshold intervals at 275W after 4 days off (minor cold): [image] LTHR is almost always 158bpm or 159bpm, unless I do a long threshold like 1x35-min and then it will show 160 or 161. Or after a month of…

I found the auto FTP toggle on my edge 1030 and just turned it on. Thanks!

Great info! I was not aware of this. I took a look at my Garmin, it said 158w. I think that’s pretty accurate for me at this point.

I wanted to poll one other item that I forgot about. That is, for people looking to target more training time at or just below VT1 (as that is where I understand one should try to be at if they are trying to follow what ISM suggests), is just doing “endurance” rides as prescribed by TR, achieving t…

Indoor I might, but if I were to the rides outside would not get close to 83% of LTHR with the standard Z2 rides from Trainerroad.

This is a hijack, but hopefully a brief one. What was it about coaching that helped so much? Accountability? Someone else’s objective view?

Yes, but the power is what you want to improve with long z2, so it will be a moving target.
