I ran the first 2 miles @ 5k pace (splits were just off by 2 seconds). Ran the 4 mile split in a PR then the wheels, as they say, came the hell off. I ended up getting chicked by the 1st female finisher. This chick even looked back at me as she passed me to pour some salt on my wounds.
You crap your pants and then you die.

If it truly is 100% 5K effort than one shouldn't be able to finish the 10K
So a 100% 5K effort should leave you dead?

Exactly. You should be seasoned enough in the 5k for your PR to be from a race where you practiced and timed it right and were completely spent in the end. It should be as ridiculous a question as someone asking what happens if they went out at 400m PR pace the first 400m of a mile. If they don't drop out by 600m, that's not a decent 400m PR.
Nonsense. These are completely different energy systems. At the end of a truly 100% 400m, you don't cross the line suddenly unable to run at all. But if you were to keep running, you would very rapidly drop off in pace, no matter how hard you tried. By 500m, you would probably be going at most half the speed that you finished your 400m. By 600m, you would be almost walking. But nothing says you have to drop out. Eventually you would reach a pace where you would actually be able to hold that pace until the end of the mile. Maybe that pace is 12 minute mile pace, but nothing says you have to drop out, you can just finish at that pace.
If you went out in a 10k at all out 5k pace for the first 5k, the drop off would be much less extreme. Your second 5k would be much slower, but it might only be a minute or two per mile slower than your first 5k.
If you think that you should finish a 5000m unable to take another step, you aren't running your best, in terms of time. You may be racing at 100% effort, but your PR will significantly improve once you learn to pace yourself properly.

If you wrap up the 5000 of your lifetime with a proper kick you won't be able to keep running - you'll have to walk for a little while then get back to running
If you actually bothered to get in better shape since the 5km race that pace might be your current 10k pace.
I believe it was Marc Nenow that passed 5km slightly ahead of his PR and finished up the 10 just fine.
