No idea if this is what you are ‘meant’ to do, but…
I estimate my top of z1 around 140, z2 around 150.
I typically run one z2 60 min session around 140-150
Another 2 or so 60-90 min or so at around 130-140 (hills dependent)
Then I try to do a longer effort 2-4 hours which usually is more walking and ends up around 120-130. Hikes typically go way lower especially when walking downhill, but its all time out on the legs I
recovery runs/ cycles etc try to keep about 100-120
