What I see is that your average pace slowed way down for a while in midwinter--to 10:15 pace or so. Yet you emerged from this period a stronger and faster runner, clearly, and ultimately notched those extremely impressive PRs. Please explain, in your inimitably clear and reasonable way, what was going on here. I suspect there's a lesson about low heart rate training.

Yes, indeed. In fact, I have to update the statement about that
in my FAQ at the end, because it's now a bit stale. As you know, my
results are based on developing massive aerobic base and just trying
to hang on to most of the speed and strength I already had. What I've
seen so far is that when I do all of my mileage well into my aerobic
zone (very low heart rates), my aerobic base continues to improve,
my pace at lower heart rates improves, and subsequently, my pace
at higher heart rates improves as well, as long as I am "mostly
aerobic" (well below anaerobic threshold, respiratory quotients in
training less than about .87). However, when I get to a point when
I'm running a high percentage of mileage (at least I believe it boils
down to percentage of overall training volume) where I'm running up
nearabouts my lactate threshold (using mostly anaerobic properties)
my pace at low heart rates withers. Since I go back to the low heart
rates for my training runs at that point (rather than just stick with
whatever pace feels right), my overall pace goes down temporarily.
So, in October/November of 05, this was my peak race time. I ran 5
marathons, one 50 miler, a 26.2k, and one 10k race during that
period (I think that covers it). Because of all the racing during those
months, my overall pace is high (although the 50 miler at an average
pace of 10 min/mile slows things down) However, all of the
higher heart rate activity withered away my aerobic base, dropping
my pace per given heart rate. Then, to put the cherry on top, after
my last 10k of the season in early December, I decided to take a
break and I cut all volume way down. As is the case when my running
cuts back, I got sick. Then I basically started back up in January,
almost from square one (but not nearly as bad as when I had first
done aerobic base building). I rebuilt from Jan through mid-February
and ran a tune-up marathon, then ran several more marathons and
ultras every 1, 2, or 3 weeks, until last weekend. In this case, I
maintained substantial weekly aerobic training volume such that
the percentage of high heart rate stuff, still remained low, even with
26 miles of racing sprinkled in. The marathons nudged my pace
down a little bit, but nothing substantial, and when my race times
are sprinkled in, the pace tends to look on the "fast" side (fast
for me, not for most of the folks here). Perhaps more meaningful
than to look at overall pace, would be to break it down in my log
to paces for:
training runs
long runs
races
treadmill runs
I've spent enough time at this now that I'm beginning to understand
the trends and they are pretty consistent. For me.
