U.S. bobsledder Aja Evans' screen-saver image needs no explanation. It's a picture of a gold medal, the one they're handing out at these Pyeongchang Olympics.

"It's been on there since they released the picture," Evans said. "Only the gold medal."

Finally, the chance to get it has arrived.

Evans is racing with Jamie Greubel Poser _ they won bronze together at the Sochi Games in 2014 _ when the women's bobsled event in Pyeongchang starts on Tuesday night. They are widely expected to be medal contenders, and it would not be a surprise if they left with gold.

"I still have more to prove," Evans said.

Getting here has proved plenty already.



Evans _ like so many others in bobsledding _ has a track and field background. After winning bronze with Greubel Poser four years ago, Evans set her sights on trying to qualify for the 2016 Rio de Janeiro Games as a heptathlete. But a torn knee ligament derailed those plans and left some wondering if she could effectively return to bobsled in time for 2018.

"Going through that rehab process and surgery, you either find out how bad you want it, or how bad you don't," Evans said. "It takes a lot to go through that rehab process from training at such an elite level to struggling to do a single leg squat and bend my knee. Being able to slow the process down and take the time to develop my body again and take a break from participating in sports, allowed me to see how much I still had in me."

She's back and as good as ever.

She's very big on imagery, and there's more to that than just the medal on her phone. Athletes are issued their podium uniform before the games, just in case there's a medal to celebrate. Evans had hers laid out in her room the whole time _ socks, shoes, pants, shirt, jacket, all of it _ and refused to touch it until she could say she was a medalist.

"I refused to come all that way and not make it happen," Evans said.

The same thinking applies now.

She wants positive thoughts only, all the way to the starting line. The last thing she'll do before stepping onto the ice is say a quick prayer with her mother, just as they have done _ in-person or by phone, no matter where they are in the world _ before every run of her bobsledding career.

"I'm not very superstitious," Evans said. "But there are things that help me stay focused and stay on that right course, and hopefully it all works out."
