I'm at the gym a minimum of 3 hours, 5 days/week...in addition to my long weekend rides which can typically be anywhere between 3-5 hours. Yes...I exercise a LOT. We'll see what happens on my ride tomorrow, with my HR & calorie burn. I'll post an update.

Linda, Prediction of functional aerobic capacity without exercise testing is used by Garmin in order to set the values for people that hasn't have a fitness test done or don't know their HR zones, it does not warranty that will set your zones correctly. I believe for you would be a good idea to check what values are set up as your max HR, resting HR and zones as these get set up by the Garmin when selecting you Activity Class at the beginning of the set up. If you know what is your maximum heart rate, resting heart rate and what are your heart rate zones, input those in your Garmin and you'll get a more accurate reading.
