stairs20:08 0.21 mi (1:38:11 / mi) ahr:133 max:149
Up and down the three half flights of stairs in my house. I didn't have anything loaded on my mp3 player that I wanted to listen to so I did this without any entertainment. I think 20 minutes is about all I can do of these without something to distract me. Did some trying to run up the stairs and some double stairs but mostly just plain since it's been quite a while since I've done these and didn't want to overdo it.
