Ran/walked for 60 Minutes

Daytime temperatures are still below freezing, so I went to the gym again today. I exercised for 60 minutes, doing 2 minutes running and 1 minute walking. The afternoon temperature when I left was 23 (F) and 19 when I returned. In 2 minutes of running I do 1 1/2 laps of the indoor track. In 1 minute of walking, I do 1/2 lap. I stopped twice to get a drink of water, I took 2 brief rest breaks (standing) and watched some guys play basket ball on the floor below the track.
