Notes
1 mi. warm-up
4 mi. fartlek (2:00 min. fast, 2:00 min. slow)
1.6 mi. cool-down
Pretty productive workout, I think. Really struggled on this aerobically, but that's expected since I haven't done any interval training in so long.
I averaged a little over 6:00 pace on the fast intervals and around 8:00 pace on the slow intervals.
