Calories are way way off
AnsweredEver since switching from Wahoo to Karoo 2, my calories uploaded to Strava are much less for similar rides. I ride with others and their calories burned are so much higher yet my suffer scores in Strava are higher than theirs. I DO NOT have a power meter on my mountain bike.
To compare, a 12 mile mtb ride 9.0 mph with 700 elevation showed 350+ calories burned. A walk completed in a similar time only at a 3.0 pace showed 560+ calories. There was no comparison in terms of the intensity. The walk was tracked only in Strava. I believe the walk was 560 calories, but no way did I only burn 350 calories on the mountain bike ride.
I have looked at other posts and all I could find is that this is tied to needing a power meter. This is ridiculous. Anything else I should be looking at?
I use a cadence meter on my road bike and that does give me a more accurate calorie count.

@Samtalya: Sorry to hear about the trouble that you have encountered and I would like to investigate the issue further.
I understand that you are not using a Power Meter. Did you pair an Heart Rate Monitor to Karoo 2 during that ride?
As you know, Calories uploaded on Strava without a Heart Rate Monitor or Power meter connected to Karoo is totally Strava's calculations and currently Karoo 2 does not calculate the Calories without a Power Meter.
To understand more about Strava's calculation of Calories, please see: https://support.strava.com/hc/en-us/articles/216917097-Calorie-Calculation

@Samtalya: Karoo 2 does not calculate Calories from the Heart rate data and it can be calculated only from the Power data. Since you do not use Power Meter, the value you see on Strava for Calories is based on their own method of calculation.
Also, If the “My performance” section on your Strava is not updated with the latest Pace and FTP it would give the wrong reading as well.
If possible, could you try uploading that ride to TrainingPeaks and see if you are getting more accurate data for Calories.

Hari,
whilst you can calculate calories from a power meter, these aren't stored in the *.fit file. and as far as I can see are only shown on the K2 display.
From your post, you are implying that the Calorie Data on Strava would come from the K2, if a power meter was used, how is this transferred?
Thanks
Dave

the thing is why does it not calculate calories on HR alone? garmin does it and its really close to my bike computer with a power meter. usually only 50 calories off or so per ride. but it leaves it up to strava and strava is way off. this is a big minus on the karoo. most people don't have have power meters and that only makes it a little more accurate.

@Steve Knight, no Idea. There are plenty of services that can manage it from HR alone, Hammerhead just CBA.
the Power meter thing is a smokescreen anyway, they make a big deal about only being able to calculate calories using a PM, I go and get a PM, and it turns out that it is only displayed on the Head unit during the ride, it isn't recorded or stored.
I'm done with the K2, I use my original elemnt as a head unit while riding and have just started recording my rides on my Garmin Watch, once the 840 appears, I'll get that (Hoping for USB-C).
Hammerhead don't care about existing customers, they're only interested in snagging new ones, this is why they focus on the big headline grabbing features rather than fixing stuff that people assume would already be present.

Hi Dave, You are correct. Calorie data are not stored in the Karoo FIT file but if the Power output is available, Strava uses that to calculate the Calories.
We are working towards including more data in the FIT files and calories is one of them. We expect to make this progress in the future.
-
Yes, you keep saying that, the mythical 'future'
You've just added a slew of new metrics to the fit file, things you actually had to write code to calculate.
The calorie data is there already as you can see it on the k2 display, how hard would it have been to include that in that update?
