And that leads us to wonder which athletes have improved the most year-over-year in the 400m and 800m.
It's been a wild ride over the 2019, but some of the most improved athletes at these distances have experienced a major boost in momentum. In the 800m, for example, Marlena Preigh, a senior from Boulder Fairview (CO) High School, went from a pretty good half-miler to an exceptional one, taking 10.15 seconds off from her best the previous year. She's currently ranked US No. 4 with a best of 2:06.80 from The Simplot Games.
Similarly, Kami Joi Hickson, a junior from Philadelphia Neumann-Goretti (PA) High School, demolished her best from a year ago, cutting 14.13 seconds from a 2:22.71 all the way down to a 2:08.58.
There's a ripple effect to competing in championship meets, and both 800m runners saw major developmental shits when faced with elite competition.
In the 400m, improvement was more subtle. But Aaliyah Pyatt, a sophomore at Fredericksburg Massaponax (VA) High School, scored a PR by over 5 seconds to finish US No. 11 in 54.87 seconds.
