Jaylah ran a blistering 14 minutes and two seconds over the four-kilometre course to edge out Queensland's Nikita Moore by four seconds on Saturday, August 24.

Her win stamped her as an athlete to watch with the IAAF 2021 Bathurst Cross Country only two years away.

It's just the most recent in a string of accolades for Jaylah, who won a silver medal at the Youth Olympics last October before being named the Young Citizen of the Year in January.

She has also won two-straight 1500-metre titles at the Australian All Schools Championships.

Jaylah said she was happy with her run after a long training period.

"I've been training since the start of the cross country season in April," she said. "There's always a bit of improvement there, but I felt I ran as well as I could have that day."

Jaylah said her winter running was very different to her summer program.

"Cross country is a lot further, so the tactics have to change," she said. "You have to pace yourself more, because if you go out too hard, there's the potential you'll blow up.

"You have to kind of run with everybody else."

Jaylah's time was just outside a three-and-a-half minute average per kilometre, but she said that didn't concern her too much.

"I wasn't really aiming for a time, it was more to win a medal," she said. "It was a very flat track up there, but very dusty, so it messed up my breathing a little bit.

"You don't usually get flat courses, but this one just wasn't as hilly."

Jaylah travelled to the event with her mum and nan, who she described as her "biggest supports".
