The competition exists out of four rounds, each with races of four or five skaters. In each round, the top two with the fastest time advance to the next round, with confirmation of a jury. The fastest competitor in the final is the winner of the event.
Maame Biney was the youngest participant, having just turned 18 years old. One of the big medal contenders, Choi Min-jeong, was also younger than 20 years old, just like Anna Seidel and Petra Jaszapati. The oldest competitor Veronique Pierron was only 29 years old, and only six days older than Andrea Keszler. Eight other skaters were born about a year later, in 1990. Sixteen out of thirty-two athletes had competed at the Olympic Games before, of which seven have had competed at least twice before. Arianna Fontana was the veteran of the group, this being her fourth Olympic appearance. Fontana went for a gold medal, after already winning a silver and a bronze medal at Vancouver 2010 and Sochi 2014. Marianne St-Gelais was also aiming to equal or best her performance of eight years prior.
There were few surprises in the heats, based on the world rankings. In the second heat, Kathryn Thomson and Suzanne Schulting crashed, causing the latter to miss the quarterfinals. In the fourth heat, Elise Christie showed her determination by skating to a new Olympic record, with Qu Chunyu surprising behind her with a second-place finish, before home skater Shim Suk-hee. In the seventh heat, Anna Seidel surprised with qualification, before Lara van Ruijven and Magdalena Warakomska, and in the last heat, the Olympic record was bested again. Home favorite Choi Min-jeong raced without any real competition, with Petra Jaszapati finishing more than 10 seconds behind her.

Quarterfinals[]
In the quarterfinals, four races of four skaters each, there was even more excitement going on. The first heat of the quarterfinals, the field was packed, with both Fontana and Marianne St-Gelais, as well as Yara van Kerkhof, three skaters of the top 10 in the world rankings. Despite a penalty for St-Gelais, who lost her chance to improve upon her performance at Vancouver 2010, the race was close, with Fontana coming out on top, in front of Van Kerkhof and Maliszewska. The second quarterfinal once again had a new Olympic record, by Christie beating her (and Choi's) time as set in the heats. Behind her, Kim Boutin showed her aspirations by finishing only 0.08 seconds behind Christie, despite a fall just in front of the finish line. In the third heat of the quarterfinals, there was little else to note, with Sofia Prosvirnova and Fan Kexin continuing, on some distance of Han Yutong and Maame Biney. In the last quarterfinal, Qu Chunyu somewhat surprised, finishing in front of former Olympic record holder Choi and Martina Valcepina, with the help of a photo finish.

Semifinals[]
Both semifinals were full of twists and turns. In the first semifinal, Choi once again set a new Olympic record, the fourth time that the old record was broken. Behind her, Fontana reached the final of the event for the third time in a row. Fan received a penalty after impeding, which meant that Prosvirnova would be the only one advancing to the B final of this semifinal. The second semifinal was kept very tight until the end, with Van Kerkhof edging Christie by only 0.002 seconds to advance to the final. The second Chinese skater Qu got another penalty for obstruction, and the third-placed skater in the race Boutin was advancing to the final after jury decision.
