I used to have an active but only occasionally strenuous job, I'm pretty sure I would have used up more glycogen in the course of the mornings work than in the half hour ride there.
My job can be strenuous at times, but I'm mainly sat at a desk. I work between 2 offices, with 3 flights of stairs in between, and I'm probably up and down the stairs between 6 and 8 times a day.
I'm no athlete for sure, although I do have a resting heart rate of 51bpm which is excellent for my age. I don't hang around on my 10k ride in the morning, but certainly not flat out for the most part. The hill is most definitely the hardest part of my ride, and wind dependant my heart rate can be anywhere between 152 and 162 by the time I get to the top, so my body is certainly working hard, and my legs are burning. It steepens to 15% at the top where I'm averaging between 5 and 8mph.
