I was wondering if there is supposed to be a correlation between the heart rate zones and the power zones? I'm going to grab some books on training with power, but I was hoping someone could clear this up tonight. The zones I am talking about are the 5, not the 7. My question is when working "Zone 2", is my heart rate supposed to match my power zone? When I downloaded my data, I noticed that I was 70% in Zone 2 and 30% in Zone 1 for power, but my heart rate was way in Zone 1 for the entire ride (99%). Are my power/heart zones set up incorrectly or is this typical?
