Hi,
I run almost everyday with a HRM-Pro-plus. Since I got it, I noticed that at the end of the run, my watch shows the power zones, however, even on easy days, it always says that I spent 99% of the time in Zone 5, while the heart rate shows that I was in Zone 3. Any idea what the issue might be(if there is an issue at all)? If this is normal, what's use could I give to running power zones at all?
