Mikaela Shiffrin will try to "reset" after suffering a second consecutive disqualification at the Winter Olympics.

The American missed a gate in her first run in the women's slalom on Wednesday, compounding her woes after skiing out of Monday's giant slalom.

Shiffrin, the overall World Cup leader and heavily fancied in both events, had only failed to finish 14 times in 229 starts across all disciplines at World Cup, Olympic and World Championship events ahead of competing in Beijing.

But these two setbacks have left the two-time Olympic gold medal winner questioning herself.

"I was pushing and maybe it was just past my limit," she said.

"I feel that I have to question a lot now. I will try to reset again and maybe try to reset better this time.

"But I also don't know how to do it better. Because I just don't – I've never been in this position before, and I don't know how to handle it."

Shiffrin struggled to fight back tears as she reflected on a dismal start to the Games, where she had started with hopes of medals in five events.

"It's so stupid to care this much,” she said. "It feels like a really big let-down.

"There were some people who expected I might win, maybe hoped I might win.

"I know that, for the people working closest to me, we were all crossing our fingers, and also doing all the work I could possibly do to give myself the best chance.

"We came all this way. And we're not done yet. But GS and slalom, those were my biggest focuses. It really feels like a lot of work for nothing."

The 26-year-old can still salvage medal glory in her remaining events – the super-G, downhill and combined.
