I was hoping to get some advice in interpreting my results for my drift tests to determine my AeT.
– 30 y/o female, running regularly for past 3-4 years most days of the week; have been on/off with various recreational sports since childhood.
– This year was my biggest training year: 600+ hours with focus on mountainous ultras, 100,000m annual vertical accumulation. I’ve done most of my training with nasal breathing, usually in a fasted state, with a few bouts of higher intensity sessions throughout. I find I’m able to keep my mouth closed for extended periods usually <=175bpm, although I’ve noticed I’ve gone higher sometimes but haven’t tested much above. I’m not sure how likely ADS is for me since I’ve spent a lot of time at seemingly low intensities.
– I did a lactate threshold field test using the Joe Friel method end of October where I ran on the treadmill for 30 mins at a constant pace @ 1% incline and determined my AnT was 195 using that method (although I find it hard to reach this HR outside and think it may actually be closer to 190 where it begins to feel very difficult): http://tpks.ws/M2IJYZNONIOCVTI4FEYTRMETSU
Recent drift tests with their starting HRs (I’ve performed all of these on the treadmill for 1hr after at least a 15min warmup at a constant 3% incline & speed. My foot pod was not calibrated well, so paces are not all accurate and should be be constant as I didn’t change treadmill settings):
– 160: 1.8% (http://tpks.ws/NJ3CG63H2AQOXTI4FEYTRMETSU)
– 170: <1% (http://tpks.ws/H2NJBRLS2XJVJTI4FEYTRMETSU)
– 177: 2.2% (http://tpks.ws/VE6N3VYI5ZG3ZTI4FEYTRMETSU)
– 180: HRM chest strap failed during the last portion, but was getting very low drift before this happened (http://tpks.ws/I3JIIYJUACQN7TI4FEYTRMETSU)
I’ve been unable to get close to 5% so far and am unsure of how to test further. For my last test starting at 180 I felt it was moderate intensity and got tiring near the end, although didn’t feel any obvious lingering fatigue after the test. I’m unsure if above that is reasonable to test as it seems quite high for how zone 2 is typically defined.
