It's not blood sugar - low blood sugar is the "bonk", and it's a killer. Any event over about 50k is long enough to use up a complete load of food - several times over on a 300k. You'll notice several feed stops in the ride report - if you're not careful the bonk can strike pretty much anywhere after you use up last night's bushel of pasta or whatever, and there's no reason to particularly expect it at the end. I think it's more just soreness, the way that riding in the dark gives little sense of progress, and what Alex calls the "80% distance blues" (which strike regardless of the total distance, it just feels like you've done the job and are just being made to suffer for the sake of it).

I never travel by car - nasty habit - although if there had been a pub open at 0100 in rural Berks I would have limped over to it by bike and had some more moist delicious beer. I wonder if I should start caching a bottle at the event HQ.
