Massive calorie burn on 10 km walk....

NOT!
Here's one of the down sides of being fitter.....
Walked 10 kms of hills with the family on sunday over approximately 2 hours, and the heart rate monitor told me I had burned guess how many calories....800 you think, 600 maybe, at least 400 surely- NOPE - a grand total of 175!
Why you ask - because my heart rate never nudged over 110 bpm, and most of the time was under 100. To help you make some sense of these figures if you are not used to HR measurements, my training zone for fitness needs to be between 116- 155, (its never at the lower end in classes) and when I run, it sits at between 160 - 170. So 100 bpm is doing absolutelyNOTHING for me.
But it did achieve something - because my legs were a little stiff that afternoon, so this hills challenged the let muscles, but not my heart.
Oh how life has changed!
