Let me see if I can remember the data from my run today. I tried to commit it to memory, but my retention skills are pretty bad.
I followed Mike's direction and put in 60 minutes at 30 seconds slower than half marathon pace. I used my best time at that distance as a benchmark: 1:43:08, or about 7:50 per mile. Goal average pace, then, for today was 8:20.
I brought Nike+ along for the run to see how it recorded the workout. Ran to my "Zoned Out Run" mix, tempo-adjusted to 173 bpm, which I estimated would put me right around 8:20/mile.
I spent the first 10 minutes going slowly, using the first mile as a warm up. Hit 1 mile at exactly 10 minutes. I counted my stride rate to be 164/min. Heart rate was light at 125-130.
Sped up a little for the 2nd mile, trying to hit 9 minutes. Did it, with stride rate coming out at 168/min and heart rate steady in the 130s. Normally, I would have sped up more long before this, worried about falling behind my target pace, but I kept my discipline and worked on form and staying comfortable.
Mile 3, increased the pace to 8:30/mile. Stride rate was just a little slower than the music tempo. Cardiac drift started to set in with heart rate elevating to 148-150. Did not stop for water. Pressed on past 3 miles.
Ran the rest of the route at an 8:15-8:20 clip, which put me right about on cadence with the music. Had to slow down for a couple of tracks where the tempo was slightly slower and I could feel myself trying to lengthen my stride to keep on the beat. (It was kind of fun to pass the time running to the beat. Made running feel a little like dancing.) HR steadied out around 148-150.
I finished right at 7 miles in an hour, which an 8:34 pace, so I screwed up my average goal pace by going slowly at the beginning; but I think it was prudent since it served as a good warm up. I don't think Mike will say I didn't adhere to the instructions.
Amazingly, the Nike+ recorded distance covered as 7.1 miles, so that's pretty good. It's still giving me credit for a slightly faster pace/more distance covered, but the error is reduced after yesterday's calibration, and I think the steadier 8:15-8:30 pace is about where it's calibrated. The error will increase as I get further away from that pace, either faster or slower. I also ran on the flats, so didn't have to worry about errors induced by hills.
Good workout. I felt good. My breathing was fairly relaxed, even when my HR was up around 150. I've pretty much gotten used to the fact that my HR beyond 30-40 minutes is going to be about 10 bmp higher with the same perception of exertion. A HR at 150 in under 30 minutes would have me feeling pretty winded and on the edge. Beyond 30 minutes, though, and it feels more like a relaxing 140 earlier in the run. It might seem weird, but I guess that's the nature of the phenomenon called "cardiac drift."
I never grabbed water during the run. 60 minutes without water is pretty long for me, but I never felt like I needed it. I sweat normally, but it wasn't too warm and I didn't feel my performance start to suffer. Somehow, Robert D. can run 10-13 miles without needing a water break. I don't know how he does it. I normally need water at least by 40 minutes or mile 5. I didn't today.
Also, absolutely no issues with the calves. A little feeling of strain in the upper quads after the run, during stretching. And my ankles were feeling a little tender. But nothing out of the ordinary, and nothing to complain about. Now, need to get in touch with Mike and see what's next.
