4x4,3,2 min fast with half recovery, 3 min b/w sets
Ugh. I almost took today off. I was just feeling so low energy and unmotivated to run. But around 7pm I decided I needed to get out the door. Definitely happy I did, but the workout was still tough. It was pretty cold and on the way back home there was a slight headwind, which was hard on the lungs. Glad to get this workout over with.
