On Saturday afternoon at the 2026 VA Showcase, Mariah Maxwell surprised even herself. In her first-ever 300m, she fearlessly jumped out an aggressive start and brought a stellar run home for a new high school national record in the event.

Maxwell posted a 36.24 to break the previous mark set by Elise Cooper (36.30) in 2025. A little over an hour prior, Maxwell finished second in the USATF 60m with a 7.28 - making the effort even more impressive.

After crossing the line, Maxwell slapped her chest in celebration. She knew it was a quick time but did not realize quite how fast. Moments later, the PA Announcer shared news of the record.

"It was actually crazy," Maxwell told FloTrack after the race. "This was my first time running the 300m, like ever, and I didn't really know what to expect. I just got in there and did my best and I mean, God is good."

Behind her, Camryn Dailey and Melaney Doggett finished second and third, respectively. They posted times of 36.70 and 37.08.

Dailey's 36.70 ranks as the US HS No. 4 All-Time Mark, while Doggett's mark will go down as the eleventh fastest time in US HS Indoor History.
