Chloe Kim: 17 year-old snowboard star wins gold in women's halfpipe

The 17 year-old X Games multi gold medallist was simply too good for the rest of the field as she posted a winning score of 98.25 in her final run to clinch her first Olympic title.

Kim, who has family links to South Korea, demonstrated her podium-topping potential in qualifying yesterday with a score of 95.50 that proved untouchable.

And she continued that fearless form right from the start in Tuesday's final with four perfect landings to take the lead after the first run.

Kim failed to land a tricky move on her second run but, with her closest rival Liu Jiayu of China falling on her final run, Kim remained top to gift her a victory run with the gold medal already in the bag.

"It's insane. I don't feel anything right now. I feel empty but I can't stop crying so I think that's good," she told Eurosport.

"Someone said to me, 'congrats on your Olympic gold medal,' and I don't even understand it myself when I say that so I think I need some time to myself because right now, I'm very excited."

Kim, who won the first snowboarding gold medal at the 2016 Winter Youth Olympics, decided her final run was the perfect time to show off her skills and produced an all out score of 98.25 in an awesome display that included back to back 1080 tricks.

"I knew I wouldn't have been satisfied going home with the gold but knowing I could have done even better," said Kim.

"So that final was just for me and to show myself that I could do it and put down the best run that I could. It is pretty nerve-wracking as this has been a dream of mine since I was a little girl."

Liu Jiayu's score of 89.75 was good enough to take the second spot on the podium, with Kim's compatriot Arielle Gold earning a bronze medal with an 85.75 effort.
