Reducing LTHR in 4 months

Hi all,

I've been monitoring my LTHR in 4 months and my LTHR keep decreasing while the t-pace is more or less the same. Below is my LTHR for the past 4 months

Month 1 - 175bpm

Month 2 - 174bpm

Month 3 - 172bpm

Month 4 - 171bpm

Is there something wrong?

That's a bit odd. You'd expect the HR to rise, not fall, if your training is such as to improve it, see https://www.trainingpeaks.com/blog/how-proper-training-affects-lactate-threshold-heart-rate/ But it's only a few bpm, and maybe just weather changes and the ambient temperature could affect that.

FWIW, over the last couple of years, where my training and fitness have gone from very small post-injury to as heavy as I've ever done in my life, the LT pace has accelerated by 45 sec/mile and the HR has wobbled between 177 and 181 in a not very correlated at all way (my max HR is 199 so those are fairly sensible values to see for me).
