I went out on the River trail and then around the airport with Bryce. It was nice to have company on the easier part of my run. I felt bad though because I missed my alarm so I was a few minutes late to get started, and then I had to go to the bathroom THREE times during our run. My plan was to start my four mile tempo at the halfway mark, but the last mile or so we were running through and around frozen puddles. Not a good place for a tempo. I started instead when we got out of that area, probably between mile 9 and 10. I actually went faster than I felt. I was cold and could feel it slowing me down, plus we had been going a decent pace beforehand and so I obviously wasn't fresh. I averaged 5:05s for the tempo and then chilled out the rest of the way. One thing I did was to try to stay in it. Around 14 minutes or so I felt kind of fatigued, but I kept checking my watch and tried not to give in and get slower without even noticing it. That is one issue I've had with both tempo runs and even 800s. Don't fall asleep.
