I know that for SS4 some Z2 rides are prescribed by HR, which is often how I do my Z2 rides anyways, but quick question based on one of my favorite rides. Climbing is one of my favorite things about riding a bike and living here in Colorado. One of my favorite endurance rides is a roughly 43 mile route with ~4,000 ft. of climbing.
I did that ride Sunday of this past weekend averaged 143 BPM and 146 watts (NP 159). Both comfortably Zone 2.
Time breakdown by zones for HR - 2:55 in Z1/Z2 and 17:00 (low) Z3.
By power - 2 hours at Z1/Z2 and 1:00 above Z2
So my question is… does this really count as a Zone 2 ride? If power creeps into Z3, but I can keep my HR down at a reasonable cadence (not grinding a huge gear, lets say 75+ rpms)? I prefer to do my endurance rides on this type of route than having to stick on the boring flat lol.
