Notes
2mi WU, 2x30 sec on 60 sec, 2x1min on 90sec, 2x2min on 2min, 2x1min on 90sec, 2x30sec on 60 sec, remainder of 7 mi CD. Whoop shows my max HR during the second 2-min burst (the slowest pace of them all but accumulated effort from all the ones before brought it up, I'm sure). It gave this run a 14.7 Strain Score.
