Simone Biles’ impact will last long after her illustrious career ends.

Biles is planning to do two new skills at the world championships, skills so difficult few other gymnasts even try them. Do them successfully, and they’ll be named after her. That means decades from now, when gymnasts only know how otherworldly she was by watching old videos, Biles will still be an active presence in the sport.

“I feel like putting my name on a skill is really rewarding just because it'll be in the code forever,” she said earlier this week, as she prepared for the world championships, which begin Friday in Stuttgart, Germany.

“It's something that I can hold on to just because I'm the one that did it first.”

Biles has already done the skills -- a triple twisting-double somersault on floor exercise and a double twisting-double somersault for her dismount on balance beam – at the national championships in August. But skills are only named for gymnasts after they’re done at a world championships or an Olympics.

She already has another pass on floor named after her, as well as a vault.

“Getting the skills named after me is really exciting,” Biles said. “Just to go out there and prove to myself that I can do them. Especially under all the pressure that will be.”

Ah, pressure. Biles might seem immune to it; she hasn’t lost an all-around competition since 2013, and is all but assured of winning her fifth title at the world championships. She will likely end the meet with the most world medals of any gymnast, male or female.

But she feels it like everybody else. And she knows it’s only going to increase in the coming months in the lead up to the Tokyo Olympics.

With Michael Phelps and Usain Bolt retired, someone has to be the face of the Tokyo Games, and Biles is the obvious choice. She won five medals in Rio, all but one of them gold, and she pushes the boundaries of what is possible in gymnastics every time she competes.

Ask her about being a global star, though, and Biles recoils.

“I feel like, if I were to label myself as a superstar, it would bring more expectations on me and I would feel pressured more in the limelight,” she said. “I just go out there and try to represent Simone, not SIMONE BILES.”

At 22, Biles is smart enough to realize she can’t control the pre-Olympics narrative. But she’s also smart enough to realize she can’t get caught up in it.

It’s the work that she controls. The medals, the fame and the commercial success are simply byproducts of that.

“Hitting all of my routines and having good execution -- that's usually my top goal,” Biles said. “I never go into a competition trying to win. I just go into a competition trying to compete like I train.”

When Biles decided to come back after taking a year off following the Rio Games, she did so to see how far she could push herself – and the sport.

She’s such an otherworldly talent that she’s actually played around with these new skills for years. It was only for fun, though, never as part of a routine and almost always into a foam pit or onto a soft landing. Even when coach Laurent Landi suggested she put them into a routine, she balked, not thinking it was possible.

Until it was.

“Laurent and (co-coach Cecile Landi) help me a lot with having me believe in myself so that I could compete them. And here we are,” she said. “I feel like it's not real, but it is.”

Fame is fleeting and medals eventually gather dust. Biles’ name, however, will be etched on the sport forever.
