|That's me, coming down.|
I did the Power Hour.
It was relatively chilly and overcast, but that kept me from getting overheated. I went out a little too fast, running up the first stairs, and it took me a bit to settle into a rhythm. I case you are wondering, these are not like the stairs in your house - think about triple in height each. 200 up, turn, 200 down. Repeat.
