"I was always around 60kg and I never thought I'd become a jockey," she said.

A few years down the track, the 22-year-old is not only one of the state's most promising apprentices, but on the verge of riding in her first Devonport Cup.

Jordan has been booked for outsider Kanji in Wednesday's $100,000 race.

"It's just awesome to get a ride in it and to win it this early in my career would be crazy," she said.

Jordan has ridden 10 winners since making her race debut only four months ago.

She messaged Kanji's trainer Kayne Milne for the ride when she saw the veteran galloper was the only runner without a jockey.

"I thought there was no harm in asking," she said.

"I've ridden Kanji before and I know he tries very hard. He'll definitely settle forward and you can never put anything past these old horses."

Jordan does not come from a racing background and her first involvement with horses was endurance riding.

"I was riding with [former apprentice] Breaana Smith and she got me onto a job with (trainer) Angela Brakey at Sheffield," Jordan recalled.

"I was there for four years and got as far as riding trackwork.

"At that stage I said I'd never be an apprentice.

"Then I went to work for Glenn Stevenson [at Wesley Vale] and suddenly it all sounded too good and I knew I'd regret it if I didn't give it a go."

Jordan's weight started to come down with "a bit of exercise and a change of diet", to the point where she now walks around at 50-51kg.

"Keeping my weight down is pretty easy now but it took a massive change [of attitude] - I had to pull my head in a bit," she said.
