Van Ruijven first competed as a member of the Dutch Olympic team at the
2014 Winter Olympics. In the
500 metres she was third in her heat, failing to advance, and placing 17th overall. As a member of the Dutch
3000 metre relay team, she was disqualified in the heats, again not advancing. Throughout that year, she had problems with her knee that compelled her to change her training routine. Three years later, in September 2017, she
dislocated her shoulder. Several weeks later, she secured her first medal at the
World Championships, when her team finished runner-up in the 3000 metre relay. At the
2019 World Championships, Van Ruijven won a gold medal in the event and was in the lead for almost the entirety of the race. However, the Dutch team were unable to improve on their result in the 3000 metre relay from the previous year and dropped to fourth place. By securing gold, she became the first Dutch woman to win a world short track title at an individual event. Van Ruijven finished fourth overall in terms of total points won at the championships. ==Illness and death==
