* Marlena Preigh ran to a meet record in the 800m at The Simplot Games in February

The indoor track and field season is (mostly) over. 

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. 

Check out how the rest of the country fared at both distances.
