Since I was out of town till Monday celebrating my birthday with the family, I gave myself a pass to not do any workouts. But then I kept making excuses through Wednesday. Ended up going to bed/waking up early which was the shift I needed; it was easy to head outside this morning, warmup on the local trail, and then do 6 rounds of 30 second sprints with 90 seconds rest in between. I tend to be a night owl, and that was a great reminder of the benefits of the weekday early wake-up.
