I ran most of the workout in zone 2 and am finally learning how zone 2 feels. Zone 2 is the Goldilocks pace, which is not too easy & not too hard. I ran the last 2+ miles in zone 3, which meant that my endurance muscles had to kick it up a couple notches, and, you know what?? It was fun!
This coming week's training plan includes a track workout and a couple longer runs, which should be challenging. I think it'll be key to take good care of myself, including a bit of post-vacation detox.
