My knees held up just fine. After an extra-cautious week leading up to the race, I decided that it was becoming more of a psychological ailment than anything else, and so I elected to be hardheaded and run it. And I'm glad that I did, my joints felt fine throughout the race -- that is, until the last several miles when pretty much my entire body was hurting from fatigue.
My running strategy was simple but effective: hold back early, then find people who look like they know what they are doing and draft behind them. In particular, I ran behind a married couple for the past 15 km -- they were looking fresh while the rest of the pack was suffering badly -- and their intelligent but brisk pacing was really key in helping me through. At that point in the race, I really didn't have the mental or psychological discipline to keep a steady pace on my own, and subconsciously watching two people with good form helped me maintain my own -- despite great physical discomfort. In some ways, the final stretch (roughly the last six miles) is a sort of "death zone" where you can look around and see people crashing, and it's difficult to sustain any kind of forward movement when your own body is beginning to shut down. There, a team -- even if it was a makeshift team, in my case -- really helped me. Afterwards, the husband came up to me, and congratulating me said, "Good running, my shadow!"
So, I made it and survived to tell the tale. I'm happy that I was able to meet my two goals (even if they were somewhat modest goals): to finish, and to finish without needing to stop to walk. Generally, I would say that the event was quite enjoyable; there were a lot of fans along nearly the entire duration of the course, there was live music at some points, and the weather held up quite well (despite warnings of rain early in the day). The final thirty minutes were trying -- in a very serious way -- but I was able to persevere, and now on the other side of the race, it's as if a tremendous burden has been lifted from my shoulders, like having just done well on an important exam. Moreover, there is a simple pleasure in having taken on a major challenge and completed it.
