A.M. Did my usual long run. Mike joined me for a part of it. Did a 10 mile tempo in the middle. The splits were: 5:45, 5:48, 5:52, 5:53, 5:58, 5:57, 5:49, 5:54,5:54,5:54 - total time 58:44. Felt like I would be able to hold the pace easily at the start, but then all of a sudden slowed down to 5:54 or so and just could not get out of the rut. There is a reason for feeling this - I have been doing 3 mile tempo runs almost daily at around 5:40 pace average. What confuses me is that I have felt quite snappy in most of the 3 mile tempos, but have felt quite stale in all of the 10 mile tempos. If it was just the fatigue, I would have felt stale in the 3 mile tempos as well. I have noticed in the 1.25 pickups that once my HR goes above 160 I start feeling uncomfortable. Possibly in the 10 mile tempo HR has to get into the trouble range eventually, and I do not know how to handle it, while 3 miles is short enough that I can bluff my way through it.
Finished the run with the kids - 3 with Benjamin, 2 with Jenny and Julia, 1 with Joseph and 0.5 with Jacob. Total of 21. During the run with Benjamin we did a few pickups that totaled a mile at around 6:00 pace.
