In total, I climbed 20 flights of stairs today at work. I went back down all 20 flights too. I did 13 up and down in one trip on my lunch break. I'd like to note that these "flights" are not your average flight of stairs going up to the second floor in your two-story house. These are actually double that. My goal is to climb the stairs of the hospital every day in December, but I've already missed yesterday, but I did climb 17 (in one trip) on Dec. 1.
