I'm just starting to get back into running. Have been doing some parkruns and the training status recommendation is to do more low aerobic exercise. So today I calculated my resting heart rate and my max heart rate to calculate the heart rate to stay on. In my case 125
I run for 80 minutes sticking between 120 and 130. I do 10 km. When I finish watch says unproductive...
My lactate threshold says 150bpm 5.15minute km
Have I got this wrong or has the watch got it wrong?
