Mikaela Shiffrin continued her record-breaking run with a 21st career giant slalom victory and 88th FIS Alpine World Cup triumph on Sunday.

American Shiffrin became the greatest skier of all time as she surpassed Ingemar Stenmark's haul of 86 World Cup wins with a giant slalom triumph last week in Are.

The 28-year-old laid down further benchmarks in Andorra, defeating Norway's Thea Louise Stjernesund by 0.06 seconds as Canada's Valerie Grenier finished in third.

That victory saw Shiffrin set the record for women's World Cup giant slalom wins, surpassing Vreni Schneider's 20, as she claimed a record-extending 88th overall triumph at the competition.

Shiffrin also moved past Lindsey Vonn as the woman with the most podium finishes in World Cup races, just a day after equalling the record, but says her most important achievement came nine years ago.

"Honestly, I think probably being the youngest Olympic slalom champion," Shiffrin, who was 18 when she won her first Olympic gold at the 2014 Sochi Games, said when asked about her greatest record.

"That was really the only record that I actually ever wanted, like really shot for.

"It happened quite some time ago, and I'm still motivated today; I still had that nervous feeling up there. I was so nervous at the start ... because you want to do well.

"And it doesn't matter about records. It's just you want to do well."

Shiffrin was interviewed by her boyfriend Aleksander Aamodt Kilde, the men's World Cup downhill champion, and somewhat lost for words when asked about her next plans after an incredible season.

"I don't know, you guys tell me. Just keep moving right along," she responded, before joking to Kilde: "We can discuss that later, in private."

Another remarkable outing meant Shiffrin finished with a career-best World Cup points tally of 2,206, only Slovenian Tina Maze's 2,414 in 2013 marks a better return in the all-time rankings.

Mikaela Shiffrin found it "very hard to comprehend" becoming the greatest skier of all time after her sensational record-breaking 87th FIS Alpine World Cup victory in Are on Saturday.

A day after equalling the great Ingemar Stenmark's haul of 86 World Cup wins with a giant slalom triumph, the legendary American moved out on her own in Sweden.

The 27-year-old was a class apart in the slalom event, continuing her dominance to make history.

A blistering first run of 50.93 seconds gave her a commanding lead and she was even quicker second time around, clocking 50.84 to win by almost a second.

Shiffrin said: "Very hard to comprehend that thought. My brother and sister-in-law are here, I didn't know they were coming. That made it so special. Holy c***.

"To the whole team, especially all the people who have helped me this whole season and my whole career, all the people who are reaching out know, it’s pretty incredible, I just want to say thank you for that."

There appears to be no stopping Shiffrin, who will head to the World Cup Finals in Soldeu, Andorra next week knowing she has achieved what has never been done before.

Shiffrin's big moment came 11 years after she won her first World Cup race.

Wendy Holdener was second, with Anna Swenn Larsson third in her homeland.

Mikaela Shiffrin tied the all-time record for Alpine Skiing World Cup wins with a dominant victory in Friday's giant slalom race in Are.

Shiffrin levelled the mark set by the great Ingemar Stenmark, the American doing so in Stenmark's home country of Sweden.

She led the way by 0.58 seconds after the first run and was faultless on the second to claim triumph ahead of Federica Brignone and Sweden's Sara Hector.

The win sees her add the giant slalom globe to her overall and slalom globes for this season and puts her in position to break Stenmark's record in Saturday's slalom at the same venue.

Speaking after her historic win at the scene of her first World Cup success, Shiffrin said: "It was just a spectacular day.

"I knew the GS globe was locked in [her only challenger Lara Gut-Behrami failed to finish her first run] before I raced, I just wanted to push and fight for it. That's amazing.

"After the overall and the slalom globe, the biggest real dream the rest of the season was the GS globe. I just tried to earn it."

Shiffrin's 86th win came from her 245th start. Her 246th could see her solidified as the greatest World Cup skier of all time.

Mikaela Shiffrin made history on Tuesday by winning an 83rd World Cup race, triumphing in Kronplatz with another giant slalom masterclass.

Just 16 days after Shiffrin equalled fellow American Lindsey Vonn's record tally of 82nd victories in Kranjska Gora, she moved out on her own as the most successful female World Cup alpine skier of all time.

The remarkable 27-year-old beat Swiss Lara Gut-Behrami by 45 hundredths of a second to take the top step of the podium, with Italy's Federica Brignone in third place.

Shiffrin is enjoying an outstanding season, with this her fourth win of the past five giant slalom races.

She was fastest in both runs with another imperious exhibition of giant slalom skiing and now stands just three victories away from matching Swede Ingemar Stenmark's record number of wins for any skier of 86.

Shiffrin said on a momentous day in the Dolomites: "I was a bit nervous for the second run, but mostly I hate waiting, and finally when it was time to go, then everything went quiet and I just pushed as hard as I could every turn.

"I was a little bit wild in some spots, but it felt so clean. I thought I wouldn't be faster [than Gut-Behrami], but I thought I could maybe be close and then somehow I got to the finish."

Shiffrin has racked up 51 slalom victories in an astonishing career, more than any other skier in the discipline, while she is only two victories shy of Vreni Schneider's record of 20 World Cup giant slalom triumphs.

Mikaela Shiffrin equalled Lindsey Vonn's record for the most Alpine Skiing World Cup victories by a woman with her win in Kranjska Gora on Sunday.

The American moved level with her compatriot by prevailing in the giant slalom in northwestern Slovenia, winning by a margin of 0.77 seconds.

Two-time Olympic gold medallist Shiffrin, who has won four overall World Cup titles, is now just four wins shy of the overall wins record held by Ingemar Stenmark.

Shiffrin led by 0.24 seconds after the first run and stretched her advantage on the second, finishing ahead of Federica Brignone in second and Lara Gut-Behrami in third.

"I was so nervous this run, I have a rash on my face because I was so nervous," said Shiffrin.

"Maybe it was because of the 82, I don't know, I just really wanted to ski it well and I did. I can't believe it.

"It was a fight. But it was pretty amazing conditions and I got a report from the coaches and they were like, 'It's really attackable, so just go for it.

"I've been in this position before and I've given it away and today I wanted to fight for it.''

Shiffrin's 82 wins have come in 233 races compared to 395 for Vonn.

The 27-year-old, who debuted in the World Cup at the age of 15, will get the chance to break the record in Tuesday's slalom under the lights in Flachau, Austria.

Shiffrin heads into that race with a 419-point lead in the overall World Cup standings.

A six-time gold medallist at the Alpine World Ski Championships, Shiffrin will look to add to that tally next month in France. Two golds would give her the second-most all-time for men and women behind only Christl Cranz. She has 11 medals overall, four short of Cranz's record tally of 15.
