Hey man, I'm not usually a grammar nazi but your mistakes in this make it confusing. "Penulimate" means "second to last." So you saying that the "3rd 200 is where you gather yourself for the penultimate 200 which is usually the fastest" doesn't make much sense. The 3rd 200 is the penultimate 200. And if you meant to say that the last 200 is usually the fastest I would have to heavily disagree. The last 200 of the 800 should almost always be the slowest if you are going for time. By far most time trial/record attemps happen as follows; out fast the first 200, relax just a tiny bit the 2nd 200, crush the 3rd 200 and hang on for dear life the final 200.
Other than dying a little bit the last 50, as you say, Brandon ran a very typical record-attempt type race.
