Thanks very much for the response Seth.

 

i don’t typically track drift carefully since i was so focused on lactate, but i do notice that when i typically started a run at say, 120-125bpm, 30 min in itl be maybe 135-145 (or more if temp is high).

is drift test more accurate than lactate?

 

also, unfortunately nose breathing test has never been accurate for me (i don’t think, correct me if im wrong). My 2.0mmol/l lactate was 30-35 beats lower than my nose breathing when i did the lactate test and remained that way as I improved my 2.0mmol heart rate over time. Even now, I can nose breath at like 160bpm, which is about 80% of my mhr

 

so I think either I’ve been training at too high of a heart rate  at 140-150bpm (based on blood lactate) to make improvements, and need to back down to walking again and use drift test?     Or, I’ve been training at too

low of a heart rate and need to use nose breathing test and run closer to 160bpm

or maybe I should keep using lactate and I’m just not doing enough volume (4-5 hours a week at 140-150bpm for the last 9 months), and that wasn’t enough to make pace improvements from my 13-16 minute miles. Mile pace heavy fluctuation due to temperature
