I should clarify, I’m wondering if there is a purpose of adding in Z3, when I’m never in zone 3 while actually performing the activity. For running, I can see the technique carryover, but not for hiking?

Also I meant 8 hours RT for 2000m on class2-4 terrain, for what it’s worth. More like 450m vert per hour on class1-2 terrain
