It depends on the type of riding. I am currently doing Zone 2 and 80/20 base training, so my HR for that training is around 135 - 145. But when doing 20% high intensity training, at that point, I just focus on the power numbers and my heart rate is where my heart rate is. I just try to make sure my Zone 2 HR and Power are aligned or power is above heart, as a sign my aerobic system is getting more efficient.
