Notes
4x(3/2/1) fartlek with half the following rep for rest.
Paces for the on portions-
4:43/4:45/4:39
4:49/4:47/4:45
4:51/4:52/4:52
5:00/4:48/4:59
Went a bit strong the first set. After the second I was thinking three sets would be fine lol. Still a decent workout though. 5:20 avg for 6.5 isn't too bad
