Day 9, Week 2, Short Brick [45min/1.75M]

Started the run part to be by distance instead of time so it's easier to finish where I want to finish.  My watch told me half the time was anaerobic.  The exercise bike display didn't work, but based on my heart heart, I seemed to have gone faster than recently, so maybe that was it.  Wait, the aerobic/anaerobic measure was for the running only.  I don't know. My heart rate during the run was commensurate with the past when it was 0 for anaerobic.  Oh, well, that's okay.  It's just a number to check for fun. I'm not using it for anything. I did increase the uptick in pace on the back end to 1 mile from .75 the past week.  My knees felt good going in and I in general felt good even though doing my long run yesterday. My watch said I only needed like 12 hours rest unlike two weeks ago when it said three days, but my heart rate then was more like 180-200s and today it was more normal 140-160s.
