3min z1

intervals:
30 sec hard +
30-60s recovery (hr below 145bpm)
- did 6 sets. rest went from 30s 1st 2 sets to closer to 60s last two. Max HR on work sets never got higher than 163 and some of the latter sets even at 158/159.

First run in about 8 months. Happy with the way if felt and aftermath. looking to start running 1-2 times per week.
