Curious if someone can point me to an answer.
I was feeling a bit tired so I moved up my recovery week. What I notice now is the simple rides of 60-75 minutes in zone 2 have my heart rate low. Essentially the whole ride was in recovery mode based on the split provided by intervals.icu. I was looking for a break so the numbers really dont matter but going forward my aim was to add in some longer zone 2 rides. Should I ride at the upper end of Zone 2 to push my heart rate up? Does it matter where my heart rate is?
