Hi All.
Back to cycling after a long flirtation with motorbikes, beer, guitars and fine foods and also some ill health, and fitness seems to be returning but I have noticed something odd. I record all my rides on connect.garmin and have been doing so for the last ten years or so.
Here is a ride from last year:
https://connect.garmin.com/modern/activity/2239182787
I wore no heart rate monitor. 2108 calories consumed.
Here is a ride from the other day:
https://connect.garmin.com/modern/activity/3337152133
Calories consumed 1011
For this ride I did wear a heart rate monitor with fresh batteries. The rides seem roughly comparable but the calories consumed are roughly half. I could rationalise this by saying that the HRM allows a more accurate assessment of the work I'm doing but:
https://connect.garmin.com/modern/activity/19898547
This ride seems again comparable but I did wear the HRM and the calorie count is much higher. 1897.
I went to this site:
https://caloriesburnedhq.com/calories-burned-biking/
Here I entered the stats for the second ride, currently I weigh 268 pounds (I am 6'3" in my defence...), 108 minutes of cycling, 22.56 miles, 12-14mph. This site gave me a calories consumed figure of 1838 as opposed to 1011 that Garmin reported.
I understand not to worry about calories consumed, all I need to do is move more, eat less etc so it's not training advice I'm looking for, I'm just really curious about the discrepancy.
I understand that there have been some glitches on the Garmin site lately, maybe I am just seeing a manifestation of this, or is there something I'm simply not understanding here?
Thanks.
