I have the Garmin four runner 15. How do you track your bike ride with calories burned etc? Is there an option on here or do u have to manually add it? If you manually add it how do you know how many calories you burnt?
Short answer is: no. You will never know how many calories you burned during an activity, without sophisticated equipment in a lab. Garmin's caloric estimates are sometimes close, and most of the time not even close.
