I could have gone a lot farther today. Everything felt great, including my knee. I still stopped it at 4.5. Still feel like I need to be cautious in order for it to totally heal. Even so, my first mile was in 6:38, the high range of my GMP (6:30-6:40). I made sure to slow it down and finished with a 7:00 average. Great day today, taking tomorrow off, then back at it next week. Hopefully this knee will keep feeling strong.
