50 trips up and down the two flights of stairs

Felt a little rough after 40 trips, but I hung in there for the full 50.

I'm trying to stay cardio-fit enough to summit Scotchman Peak as soon as the snow has melted off. It's a pretty strenuous climb - about 4 miles and 3700 ft of elevation gain.

But it's on my bucket list, so to do it, I need to drop weight and be fit. I'll post pictures when it gets done.
