Putting a quiet end to a difficult Winter Olympics, Jamie Anderson of the United States failed to advance to the women’s big air snowboarding final on Monday, a disappointing finish after she earned a silver medal in the event’s debut at the 2018 Winter Games in Pyeongchang, South Korea.

Anderson, 31, fell during her first two runs before landing her third: a front double 1080. But big air combines the best two scores out of a snowboarder’s three attempts to produce a final score, and Anderson’s performance was only good enough to put her in 12th place, briefly.

Soon she was bumped down to 15th place and out of contention for the 12-woman final, which is scheduled for Tuesday at Shougang Park in Beijing.

“Honestly heartbroken,” Anderson said. “Such a high high when you do well here, and the worst low when you can’t pull it together.”

Anderson is a two-time gold medalist in slopestyle who earned a silver medal in the 2018 Olympic debut of big air. At these Olympics, though, before stumbling in big air, she finished ninth in slopestyle.

“I just straight up couldn’t handle the pressure,” she wrote on Instagram after the slopestyle final. “Had an emotional break down the night before finals and my mental health and clarity just hasn’t been on par. Looking forward to some time off and self care.”

She is one of several high-profile athletes who have expressed vulnerability over the toll that expectations and training can take. In the days between her slopestyle disappointment and big air, Anderson posted a photo of herself smiling on Instagram.

“Olympic reset!” she wrote.

Zoi Sadowski Synnott of New Zealand, who won the gold medal in slopestyle this year, had the highest qualifying score in big air. The slopestyle silver medalist Julia Marino of the United States did not compete in the event because of an injury sustained during training.

Hailey Langland, who finished 12th in the big air qualifying round, was the only one of the four Americans competing to advance to the final.

Asked if she would retire, Anderson, who lives near Lake Tahoe in California, said she did not know. “Part of me just wants to quit,” she said. “Part of me wants to go work harder and come back and win everything because I know I’m capable. But it’s been a long journey for me. I’ll definitely just take a little time and go freeride with some pals and then reset and see what I feel.”
