Flatt was milliseconds away from breaking the 800m so that one for sure.
3200m/2 mile should go down very soon. Handful of kids have scraped close to it. In addition, XC times are going down overall which lends to longer distance records also going down over time. Lots of kids in sub 15 5K shape poking around at these records.
3000 feels soft. Anyone capable of doing the 3200 should also be attempting this. Bonus benefit is you can sneak into some pro races potentially for this attempt vs the 3200/2 mile being only HS kids.
Sprints (100-400) feel out of reach (barring doping obviously). 400 record is absurd btw. Don't think anyone is touching that for decades. 44.69 is a low end pro time.
