I have just recorded two following activities (I am 42 years old and seriously fat / 108 kg):
- Hike: 9.04 km / 1h20m / 90 m elev. / 1,220 kcal
- Bike: 20.26 km / 1h25m / 146 m elev. / 837 kcal
Is this kcal burnout on second activity accurate / possible? Only 837 kcal when compared to 1,220 kcal on hiking?
Here is a Strava's (no power meter) screenshot from my hike / walk:
And here is the second activity (bike riding):
For me it was:
- Hike: a moderate walk, feeling good, no stops, my muscles moving just me
- Bike: tough ride, a few stops, my muscles moving me and +20 kg bike
How can I burn much less (only 70%) kcal on a really tough bike ride when compare to fairly moderate walk? What am I missing here?
EDIT: To clarify after a great number of even greater comments. Both numbers and "fast" wording are just to underline the difference here. I am not challenging each single kcal burnout on its own. It is only very hard for me to believe / understand that during a fairly simple walk I supposedly burned out 150% of the kcal that I burned during a bike ride from which I returned totally wet and "wasted".
So the real question could be: How can I burn way more calories walking than I burned during biking?
