The run itself went well with my pace slightly increased since the first run. Monday's run finished at exactly 2 laps (approximately 1.6 miles according to Google); today's run finished a little ways past that, so I went ahead and completed the third lap accompanied by a few of my own mp3s.
I found the first 3 minute run to be slightly more difficult than last time; by the time Laura said "slow down" I was huffing and quite out of breath. The second 3 minute run wasn't as bad though and I had enough energy to push my speed a bit during the final 60 seconds.
