Last night I started the Couch to 5k program. I wanted to run outside on Stanford’s track, but it was a bit chilly and I didn’t have warm running clothes, so I ran on the elliptical instead. It’s a half-hour program with 5 minute warm up and cool down, with alternating 60-second runs and 90 second walks. Results: easy-peasy; probably too easy for me. It’ll be more difficult on the track, but if I’m running on the elliptical I might skip ahead a week or two until it gets challenging.
