Hi, I use my Garmin Forerunner 220 for all outdoor activities, running and cycling. When running, it calculates calories burned pretty accurately. When cycling, however, it wildly overestimates the calories burned. I have to go to my computer, open up the activity, zero out the calories, then tab around the different fields and a new, vastly different calorie count will appear.
Example 1: The activity title "Richmond," a 64-mile bike ride. https://connect.garmin.com/modern/activity/1175461511
When I import it from my Forerunner 220, it displays a calories burned number of 8,419. When I open the activity on the computer, zero out the calories, and tab to another field, the calories burned number changes to 3,688 -- less than half the original number.
Example 2: The activity titled "Williamsburg," a 66-mlle ride in the other direction. https://connect.garmin.com/modern/activity/1174276029
When I import it from my Forerunner 220, it displays a calories burned number of 8,720. When I open the activity on the computer, zero out the calories, and tab to another field, the calories burned number changes to 3,682 -- again less than half the original number.
Why are the calories estimates so far off? Thanks.
