I'm following the Garmin Coach Running plan that suggests a workout for you every day.
I have the zones set up as indicated in each workout. I've realized that it's useless to follow the heart rate zone that it recommends, since it ends up marking more of a training effect than the one prescribed.
I see that it's easier to set a maximum alert and not exceed the heart rate recommended every day.
How to calculate the TE? By zones, by maximum heart rate, by pace...
