My question has to do with electronic calorie counting. Up until now, I kept track of calories burned using my Apple Watch. On my outdoor rides, it uses GPS speed data along with my heart rate to calculate my calorie burn. I didn't have a power meter to compare it against.
Do any of you that have Apple Watches and Power Meters know how well the Apple Watch does compared to a PM and HRM together?
From what I understand, a PM is supposed to be super accurate as measures the energy expenditure thru the work done.
If you have a PM, does the HR even matter?
Just curious.
Thanks!
PM vs HR calorie estimate aside, Apple Watch is complete garbage at tracking speed/distance/hr. On the same ride/hike we usually have 25% distance difference between 2-3 apple watches. Getting a proper cycling computer (garmin or similar) with right sensors will give you immediate accuracy boost. Also if you use Strava, it does a reasonable job at estimating your Power numbers.
