I honestly don't regret the fade pacing at all. Despite believing that

3:21 was highly unlikely as a finishing time, I was undecided until in

the corral about whether to pace with the 3:20 bunny, 3:30 bunny, or

go alone, but was leaning to the 3:20 choice. Once I chose opening

3:20 pacing, I believed there was a good probability of the last 10km

being a death lope or worse, and it turned out to be pretty severe but

I don't think felt as bad as 2007. This pacing allowed me to really test

my limits, I wasn't going to BQ anyway today (3:21), it allowed me to

run for quite a while with fitter looking people at a better jogging

pace, refresh my familiarity with moving forward on totally spent legs

etc. 3:31 is a BQ for me in September, so this result shows I can

quite easily do that if I choose, using a more conservative pacing

especially on an easier but IAAF-legal course (e.g. Toronto

Waterfront) with equally favourable weather.

After catching the 3:20 bunny in the first km (the initial 10m gap

grew much larger as the race started due to congestion), I followed up

to around 24km. For some reason the bunny paced the first 5km at 3:12

(4:34/km) pace but I wasn't about to let the bunny get away. I found I

needed to stop sometimes at water stations to get enough fluid which

the bunny did not do so often I would need several minutes to catch

the bunny again.

I spent most of the time for the first 30km or so concentrating on

keeping my mechanics in as good order as I could. Most people around

me had far better mechanics though there were a few other defective

runners. I remember the cambered exit or on-ramp being quite a

challenge. I found the numerous downhills challenging as usual, and

worrisome, wondering what toll all this pounding would take later

on. I had no real complaints from the body for the first 25km except a

few hints of abdominal cramps. I was taking gels every 30-40 minutes

or so, consuming in total 5 (compared to 1 in my last marathon).

I thought I might stick with the bunny until 30km but at 24km I had an

abdominal cramp which forced me to drop pace and stop for 30 seconds

once or twice. Since the bunny pace was already the fastest I was

willing to go, this meant the bunny was gone for me.

A nice progressive linear fade in my pace started at this point,

25km. The first 5km was a voluntary fade. I wanted to relax and lose

the ab cramp susceptibility. Also worrisome signs of fatigue were

starting like a tightening left outer quad which seems to be the most

significant direct cause of my big fade. Much later the right one

started. This is the same as what I experienced in 2006 and 2007. I

would expect it is glycogen depletion in those particular areas of the

muscles, and coming on relatively soon due to agressive pacing, but

perhaps there are other things going on which could be addressed with

targetted strength training. Running more efficiently at this pace

would also probably help. If it is glycogen depletion in the muscles,

then more agressive carbo loading might have been good for a couple of

minutes since I didn't do that as agressively this time.

At 31km I ran by my daughter, then surprise again at 34km. That is

appreciated of course, and now I can ask them just how bad and how

funny I looked. Somewhere in 31-34km I stopped for a few seconds to

stretch my quads.

I was watching for McShame to pass me. He may well have been ahead, but

I suspected not and I was correct. I guess he did pass me but I never

successfully recognized him.

In the last 7km my ability for any kind of stride length was fading so

I upped the cadence by feel. The watch log shows I maintained 184-186

in the last 7km compared to 175 earlier (typical for MP) despite much

slower pace. I have little doubt this was a good idea. The speed was

determined by cadence and my stride length was at maximum. I'm sure it

looked pretty funny and painful. Despite using this technique, the

very mild downhills were still very ugly. People were passing me but I

think there is fade going on in most of them as well and the speed

differential is not very high. It doesn't bother me at all. More of a

concern was if one of those passing runners or one of the sub-1:30

half marathoners who I think were merging even lightly bumped me, I

would probably fall over. I wondered if I would make it to the end

without walking or having to collapse. I did manage the last 7km

without any walking or stops except one stop at a water stop for the

drink. I was watching for the the 3:30 bunny to pass me in the last

1-2km but missed that somehow. Somehow missed seeing/comprehending

the elapsed time on the watch (auto-cycled display) in the final

stretch. I thought I would be under 3:31 or even 3:30 based on seeing

4:59 average pace. Perhaps if I knew I had a shot at under 3:31 I

would have been able to speed up to meet that. I may have had another

minute in me but that is about it and I suspect it would have a big

cost. In the end, my average pace for the last 12.195km of progressive

total bonk was 5:29/km or right about comfortable LSD pace though it

felt very different.

Under 3:31 would have been better but reasonably happy with this

result though I must say I was completely sick of marathon training

more than a month ago. That's just me, I'm sure it's just great for

many others. I'll probably do another or a long trail trip at some

point but I'm in no big hurry. Now onto recovery, trails, swimming,

tri-a-tri cheering, ...
