Jess Ashwood is motivated by greatness. She doesn't have a great deal of choice, particularly when greatness tends to be swimming in the lane next door.
"Swimming" may be underselling it when it comes to US superstar Katie Ledecky. "Soaring" may be a better word. Or "cruising" like a millionaire's speedboat. 
Since her breakthrough win in the 800 metre freestyle at the London Olympics as a 15-year-old, Ledecky has been an unstoppable force in the pool.
She has broken her own world records in the freestyle distance events time and again, sometimes so effortlessly it looks as though she's doing it for her own amusement. This year alone, she has dropped her own 800m mark by more than four seconds.
All of which makes you wonder what it's like to run into Ledecky in the heat of competition? Ashwood will have that pleasure, or pain, in Rio as she tries to make inroads into the seemingly insurmountable.
But the 22-year-old is hardly the type to be deterred. With Ledecky smashing through barrier after barrier, Ashwood said it was only dragging competitors forward as they tried to keep pace.
"Once someone breaks a mark, everyone wants to lift and try to get there as well," Ashwood said. "Sometimes it gets to a point where that might not be possible. Then, when someone does it, you realise it is possible and you want to get to that level too."
Ashwood made the Olympic team for London but failed to make the final of the 800m. In Adelaide this week for the Rio trials, she had already booked a ticket in the 400m and will be hungry for more success as she steps up to her pet event.
And any step she takes has been in the context of overcoming severe curvature of the spine, which has forced her to change her stroke and swimming style, as well as restrict her from a host of traditional land-based training techniques.
Bronze at last year's world championships in Kazan was the most promising of signs as she continued to lower her personal bests. Still, there's Ledecky, who often seems to be in a race of her own
"I swam next to her in a 1500m heat. I touched the wall and made the final. She got the world record. I was like: 'Did you just get the world record? Good for you. I made the final!' That's good for me. You do your thing.
"She's doing great things for women's sport, you have to look up to someone like that. I respect everything she's doing and she's doing an amazing job."
Respect ... not fear. The pair may share a podium in Rio, and Ashwood hopes to take at least one step up from bronze to silver. And like Ledecky, she's trying to ensure the race she swims is her own.
"She is very good, so it's good motivation," she said. "You can only control what you do and what you do at training. I just try to get the best out of my own training and as a racer. I can only keep working towards my personal bests and I'll be happy with that."
