Garmin Connect & Calories burned?

n1ckster

Good morning,
Can anyone offer any sort of explanation as to why 2 not dissimilar rides and efforts have produced such different Calories Burned figures? Below is a screenshot of a ride yesterday and one this morning, along with a number of other metrics.



Thanks in advance,
Nick

Because they're a load of nonsense.

because of Saturn's position in relation to Venus.

Garmins kcal count is clown shoes...the closest you can get to actual kcals burned outside of a lab is with a power meter. If you think about 600-800 an hour you're on the right track.

You can't have more than 100% Max HR, clearly your max HR is more than you have put into your garmin profile.
as DavidJB said If you want to have a better idea of calories burned you need a power meter

I second using a PM for accurate calorie expenditure. Best way with going into a lab.

More like 500kcal p/h.

And I'd love to be able to pedal at 190 rpm, as it thinks you did on the first ride. I think you've got some garbage going in, and some garbage coming out.

I think its fashionable to have a 'calorie counting device'. Have never quite worked out why. I think they just grab a number out of the air and double it

I ran Beachy Head Marathon on Saturday and my Garmin said that I burned approx 3100 calories, but the same data fed into Strava concluded that I had burned about 4150 calories.... neither are probably true.

Yeah as a v rough guide I reckon: 500 ph for a steady ride, 600-700 for a rapid ride, 800 for TT'g / racing.

It really depends on your level of fitness and general physique. If I'm out for an hour sprint trying to avg. zone 4 I'll be 800+ p/h. However, a normal training ride of 2-3 hours I'll be more like 500. The less fit you are the more likely you are to burn more for a given task, but only up to a point.
