Did 3 easy in the morning. Then in the afternoon was planning on doing 3x2 at 5:00 pace. The first interval was in 10:11. Then I realized that if I did the whole workout, I would end up with 15 miles for the day. So I did one more interval, but made it a half mile longer. My total time was 12:40-ish. After the first mile a little sub-5, all I could do was 5:20 pace.
