Good run tonight, even with the lack of sleep from working the night before and putting in a full day at the office, plus running the hills last night. Took a nap when I got home then laced them up and told myself to run in the 145bpm zone. I sensed I was running fast but the effort was easy while in the 145bpm zone. Still too early to tell but it's looking and feeling really good. Happy about the splits, especially the last 4 miles were pretty even across the board and in line with my HR.
