Ran 3 miles of speed workouts consisting of 6x800 meters with a 400 meter jog at 7:30 mile pace in between intervals. I don't know what it is, but this workout killed me. I pushed as hard as I could, and still did not achieve any extraordinary times. My splits were as follows: 2:22, 2:30, 2:32, 2:34, 2:37, 2:37. This was dissapointing because I would have liked to break 5:00 min mile pace, but thats the way running is sometimes. I think that the lack of a good recovery before the following interval is what really did it. Previously, when I did speed workouts, I would only run 12x400 with a half lap walk, which gave me plenty of time to recover. Today, I felt tired even before beginning the next interval. Even though my times were dissapointing, I still felt like I got a good workout. |
