The longest stretch was 1 mile long, most other streets were like quarter to half a mile, before slowing and having to make a turn
My apple watch said i burned about 430 calories, online calculators all say roughly about the same thing. My heart rate was 135avg, and 150 max

Then on the other hand when I read power meter related calorie burn from people whom have a power meter, it seems like it is much less than that.
However it seems like power meter doesn't take into account, the heart rate or your age , gender, and weight.

So, how much calories do you think i really burned?
Also, is factors like gender, heart rate, and age not taken into account?
