This was a 1mile/1min/3min/1mile speedwork session where I just ran the 1 minute "really fast" and backed way off on the 3 minute recoveries (10min/mile+). I also cut the cooldown about a quarter to a third of a mile short because I didn't want to skyrocket the HR going up the hill to the house.

I was a little surprised when I saw those interval paces above...I didn't realize I was running that fast, especially the sub-6min/mile one. I also liked that my later intervals were faster than the earlier ones.
