Also, I would like to say...I bet the results in the gold womens race reflect the same time difference. I would predict the average PR of the top 25 in the gold womens race would be somewhere in the 33-37 second range. I would encourage you to do the research and calculate the average. I guarantee I'm right.
The data does not lie. Look, I get the course is designed to be fast. I have likewise ran on courses that are designed to be fast. They don't have much hills, they're wide with short grass, and don't have a lot of turns. I get it. But a short course and a course designed to be fast are NOT mutually exclusive. If I had the time to go down to Alabama and measure this course I would, but I don't. The only other way to look at it to see the if the course is short is the results, and the results say 25/25 kids in the championship race are setting PRs by an average of 171m or 30.4 seconds. The data does not lie. I honestly do not care that this course was rolled with a steamroller, it could be rolled with a million steamrollers, that doesn't change the fact that the data says something is not adding up in the course. Lets not kid ourselves that that is the reason kids are running fast. Look at Colin Sahlman's splits for example. He runs 4:29.78 first mile, the 2.1 miles are run in 5:11.60, which means he slows down to 4:42 pace which is 14:36 pace. Do we really think this is realistic that he slows down that much? Almost every athlete has the same large slowdown in the second mile. Then he splits by far the fastest mile of the race with a 4:21. What athlete sets a "record" with this kind of pacing? What are the chances that almost ALL athletes had a similar slowdown and pickup. The data does not lie.
