Thanks for the feedback. Run didn’t feel any harder, both felt super easy since I usually run on steep terrain at much higher heart rates. I’ll try it again at 150 bpm and see what happens.
Well, this is weird. I repeated the aerobic threshold test at a higher target HR of 140. This time Pa:Hr is even lower at 1.2%………it was 2.4% with a HR of 135 in my initial test.
Thanks for the confirmation. At around 140 bpm, I guess my aerobic threshold seems higher than what I expected……hopefully this means I have less work to do to develop my aerobic capacity.
