Last week, we took a look at trend lines for high-end performances in cross country and the track distance events (1600, 3200). I started thinking it would be interesting to do this outside the circle of distance events as well.
So, today, we pay a visit to the 400 meters. I've identified 48 seconds for boys and 56 seconds for girls as a kind of "elite" standard. Just a bit lower on the ladder, I've identified 50 seconds for boys and 58 seconds for girls as high-end, but achievable for many athletes, standards.
As I did with distance events, I went from 2009 (the first year of essentially complete meet results on Colorado Track XC) forward, tracking the number of athletes to exceed each of the standards in the paragraph above.
This time, we'll start with boys:
Boys 400m Performances
Girls 400m Performances
