Got going very late (after midnight) on the stairs.

As I was going up and down them, it occurred to me that I get off night shift this morning, and it would be more fun to go on a bike ride later on than to grind out 50 trips on the stairs - and it's unlikely that I will have the energy for both.

With that thought, I stopped at 20. Not much of a work-out, although I did break a sweat.

2 flights x 20 trips.
10 minutes even, heart rate 153.

After I get some sleep in the morning (hopefully!!!!), we will see about a short road or mountain bike ride in the early afternoon.
