I knew I was getting in better shape from cycling, but I didn’t know how much better until tonight. When I ran for the train.

When I’m not bike-commuting, I take the commuter rail and the red line. Tonight I needed to catch the 8:15 but didn’t get up from my desk until 7:55. When the red line got to South Station, I ran up the escalator to jump on my train.

That probably sounds uneventful. But six months ago, I couldn’t sprint up a long escalator without losing my breath. It was such a change I could hardly believe it…

…which was reassuring, given that I haven’t lost as much weight as I expected.
