Well today, we did a gentle long hill which...bewildered us, because we were panting unnecessarily.

Dearie reminded me that Calgary was at a higher elevation than Vancouver...1,000 ft. higher for whole city.

It was just so strange....since I knew the grade was no more than 8% which is normally easy for me.

So the lesson is, a new city /area might be overall at a higher elevation than old place. So first day or so, you might notice certain effort on certain hill climbs.
