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

It is a rough estimate, from a WKO report I wrote to extract the zone2 portion of rides with low IF and low VI (without having to tag them). To improve accuracy I am in the process of properly tagging past rides. And some context is missing - don’t read a lot into peak ftp because this year my seaso…

Well I’ve just had a bit of a reality check on my estimation of LT1. I’ve been try to pin it down for almost 12 months using RPE, Xert LTP, Talk Test Alpha1 etc and had it pinned down depending on the method to 160-19W and 132-140 bpm. I decided after much internal debate to buy a lactate meter. I’…

Could also be an off sample or you might make a lot of lactate. Try another test with at least two higher levels. (Base, 145, 165, 185). I would do 8-10 min steps and include a long warm up as well. For the sample, make sure it’s a nice blood bubble and that the test strip only touches the blood. …

Yes, sounds like an off sample. Probably have touched the skin. Have you wiped away the first drop? Always take from a second drop. There is a learning curve with this. It took me a while to get consistent readings. If a value is obviously too high the strip got contaminated by touching the skin or…

[image] nexusone2012: I think for me improving Zone 2 endurance is rooted in health and metabolism first One thing I forgot to mention is HRV and RHR. In the process of switching to a more endurance, fewer intervals approach, my HRV is now actively moving in response to recovery and hard bloc…

[image] WindWarrior: The primary change in my life was switching to more endurance. Doing more volume with extra Z2? Or less intervals in the form of sst/FTP?

Ime, contaminated drops produce an error message or a reading that is several mmol different. Best thing for @carytb to try is several points below that power level to get at least 3 points below lt1. Start at super easy power level and only move uo in power gradually.

Look at the sample two weeks in this FasCat plan: Sweet Spot Part 2 – FasCat Coaching Or look at the weeks in Time Crunched Cyclist book (I’ve got the 3rd edition). Same pattern as Coach Tim Cusick’s full season masters plan that I bought. Essentially it’s having two key endurance workouts per we…

[image] WindWarrior: Essentially it’s having two key endurance workouts per week, and two key interval days, and 8-12 hours per week total. I am in a 4week block of 4 endurance days and 2 interval days (14-15h). Then 1 recovery week…

How badly do you want to know? I did a deep dive on dfa a1. In the end I basically triangulated my LT1 with a1, the talk test, and Seiler’s 60-70% of HRmax. They were all in the same ballpark.
