Mon 9/4 - PM about an hour, incl. 8x60 seconds on Heartbreak Hill

Feeling tired after a less-than-restful night's sleep, one too many 5k races in Lowell also taking its toll. Quickly reminded of how much I dislike running up this particular hill. Also did some drills beforehand, mildly strained my gastroc running backwards. Glad to get out of there at the end of the workout.
