Calorie calculation based on known values (Garmin Fenix) and expected MET rate

Does the Fenix 6 integrate with any tracking apps?  I feel pretty sure that it does, so that’s probably your best bet if it’s an option.  The app I use (Suunto) has that kind of data processing.

What exactly are you referring to? How do you calculate calorie estimates for future trips with suunto, based on your historic data?

It’s pretty easy: Suunto’s dedicated app automatically syncs all of the watch data and processes it into graphs that show either historical data/trends, or estimates of what I need to do/change in order to perform equally in the future, perform better, rest and recover, etc. Everything from caloric consumption to ascent/descent/ to pacing/HR/VO2 to how well I sleep at night is displayed graphically and numerically in the Suunto app, so it gives me a nice, quick snapshot of how I’m doing on a variety of metrics. So, yeah: I just look at the logged activities – hiking, trekking, training, etc. – and see what my caloric burn was for any given activity and any given conditions, and I start making estimates.

Hi Christoph,

You can use this this MET Calculator. You provide your body weight, length of your activity and pick from a list of activities. My Fenix 6 is showing me ‘2,117 calories burned’ during a recent 15 mile hike in the Sierra that took 5:20 hours. With the calculator I get 2,116.77 kcals for my 175 lbs weight when picking ‘Walking’ as my activity with the description ‘Carrying 1- 15 lb load upstairs’ for 320 minutes. Close enough I would say :) When I pick ‘Backpacking’ as a description for my type of ‘walking’ I get a higher number which is most likely due to ‘normal’ backpacks weighing way more than mine.

Agreed.  On a calorie-tracking app, I found selecting vigorous hiking to give a more accurate output for UL backpacking than “backpacking”.
