Let me start by saying Daschbach is a beast and total stud. It's rare to see a HSer with such a massive last lap. That being said, I saw a comment in the thread about his sub-4 that I hadn't realized at the time. The runners started the mile in lanes (I believe the idea was because of Covid-19 they wanted to space them out). That's against the World Athletics rules of the sport. https://ibb.co/ZT981NR I can't believe I didn't realize this at the time because I've always hated the way the mile starts, felt it was ineffecient and felt it should be run in lanes. But just because I want something doesn't mean it's legal. I've always said the mile is the most inefficient start of any. A massive field lines up 9 meters behind a curve and then gun goes off. You waste so much energy at the start because a) there often is a fight for position and b) you often run so much extra ground on the first turn as many runners are way off the rail. Take a look at how much extra ground people are running at Pre in 2019:https://ibb.co/WKM0Gg9 In a 1500 meters, you at least have 100 meters to get in position before you have to start running extra distance on a turn. In the mile, you have 9 meters. Now in a smaller high school race, you aren't going to run as much extra ground but there still would be some jostling and extra distance. And one can certainly argue that perhaps the rules of World Athletics aren't what one refers to for a US HS race but the fact is none of the other sub-4 miles in US high school history started in lanes. Editor's note. Read below. Rojo was incorrect about this. Jim Ryun's sub-4 in a HS only meet was started in lanes. Here is the WA rule :
