She placed 30th at the 2014 Winter Olympics and 24th at the 2018 Winter Olympics. Williams is the first figure skater from Brazil to compete at the Olympics[1] and the first South American skater to ever reach the free skating segment at the games.[2] She retired from competition in October 2021, after failing to qualify to the 2022 Winter Olympics due to a foot injury.[2]
Isadora Williams began skating at the age of 5 falling in love with the sport[4] while skating in a public session at the Cooler Ice Rink in Alpharetta, Georgia. She competed domestically for the United States as a child at the juvenile through the intermediate levels until 2009.[5]
In September 2013, Williams competed at the Nebelhorn Trophy, the final qualifying competition for the 2014 Winter Olympics in Sochi. She placed 8th in the short program and 14th in the free skate, finishing 12th overall. As a result of her placement, Brazil received one of the six remaining spots for countries which had not previously qualified for a ladies' entry. This was the first ever ladies' figure skating Olympics entry for Brazil.[7] Williams finished in last place (30th) at the Olympic contest.
In the 2016-2017 season, Williams earned the first gold medal for a Brazilian skater in an international competition at the 2017 Sofia Trophy.
During the Olympic tournament, Williams made history by finishing 17th in the short program, enough to become the first Brazilian and South American to ever take part in the skating final.[2] She placed 24th in the Free Skate and placed 24th overall.[10]
She also became the first Brazilian and South American female skater to ever advance to the final segment of a senior World Championship at 2019 Worlds in Japan. She placed 24th in the short and in the free, finishing 24th overall.
In 2021, Williams failed to qualify to the Olympic Games for a third time after withdrawing from the free skating at Nebelhorn, where she placed 32nd after the short program. Later, she claimed her foot had become injured during the off season and it was taking a long time to heal. This was her last international competition, as she announced her retirement plans shortly after.[2] She stated her wish was that the last competition of her career would be the 2021 Brazilian Nationals,[2] but she didn't manage to recover in time and withdrew her entry.[11]
