Something New: A Track Workout

I got a call from Maija on the way home from work Friday. She and Todd were thinking of doing a track workout Saturday morning. This is good, I always seem to skip my interval/speed workouts if I'm doing my own thing. I think the last/only track workout I've done was Jr High with "Coach", on the cinder track 25 years ago.
So we plan on a 6AM start at the track.
Surprisingly enough, I wake up 10 minutes before my alarm. Wasn't sure what to eat, yesterday I didn't eat enough before going to the pool... I had about an hour, so I took my chances with my oatmeal & fruit mix. That worked out well.

The workout was: (Maija can correct me on this)
4 laps 10K pace. (which you can see I ran faster than I should have)
4 laps 5K pace for the first and faster for each of the next 3.
4 laps all out.

I wasn't sure how I was going to do, but overall I'm pleased with the results.

I think it's funny how uneven my pace is during the all out set. I'm definitely not familiar with what I can do there. I guess I should have figured what "all out" really means. Should my pace be falling off at the end because I'm dying?

On the All Outs (9-12) What it looks like to me is #9,#10 are builds. #11 I thought I had good pace but it was slower. Then #12 I got back to putting it all out there but doubted myself and pulled back a couple times.
The graph also has me thinking it's time to reevaluate my HR zones. A year ago I would run all out and 188HR was the highest reading I'd hit. I hit 191 on that last run today and at the Mooseman I hit 196.
We are going to try for 1 track workout a week. I'm looking forward to it.

Oh, as for total miles with wu and cd 6.7 miles. I had thought it was less until I realized I turned off my watch between the warmup and the main set.
