My goal is to burn at least 1000 calories..

How much weight are you trying to lose? Or maybe it's not really weight, but more clohing size. After all, muscle weighs more than fat.

I just would like to add that when I was unemployed, I was cycling over 2 hrs. daily. Yes. So I was cycling 45 km. daily most of the time. It included a couple of reasonable hill ascent --8-10% grade.
This type of increased cycling was over 8 consecutive months...which means not including winter since I did cycle but 50% less daily. Then there were 1-2 days I increased to 60 kms. per day.

My diet didn't really change. I think I might have lost 3-4 lbs. It swung back and forth, but then I only weighed myself a few times per month. I wasn't aiming to lose weight. Just had some time and needed to keep motivated while job searching.

You have very high expectations of self @ burning 1000 calories daily plus your regular work at OT.
