Sports and health
The king encourages Danish participation in sports. He is a patron and honorary member of various sports organizations, and a former member of the International Olympic Committee. He also promotes an active lifestyle in society.
Frederik is an avid sportsman, running marathons in Copenhagen, New York, and Paris, and completing the 42 kilometers with a respectable time of 3 hours, 22 minutes and 50 seconds in the Copenhagen Marathon. In 2013, he completed the KMD Ironman Copenhagen in the time of 10:45:32 and is the first royal person to complete an Ironman.
Frederik is a keen sailor, being an accomplished Farr 40 and International Dragon skipper. At the 2003 Dragon European Championship, where 51 boats participated, the Prince and his crew had been leading after four out of six races; they finished in fourth place. At the 2008 Farr 40 World Championship with 33 boats participating, Frederik and his crew also took fourth place. Helming the Swan 60 yacht Emma, he won its IRC category in the 2010 Fyn Cup in Denmark, and was fourth in the 2011 Danish Dragon Championship with Nanoq. 27 boats participated.
In 2016, on the subject of the Olympics in Rio, Frederik told the press that he did not regret not chasing his dream to compete in the Olympics after meeting his wife. He had always thought about training and competing, but that would have required him to limit his activities and concentrate on training, instead, he put his energy into other aspects of life. In October 2016, Frederik had to cancel his appearance at the royal reception for the Danish Olympic and Paralympic athletes after he fractured his spine while jumping on a trampoline with his eldest son.
Frederik took part in the relay event during the 2019 IAAF World Cross Country Championships in Aarhus in March 2019.
Frederik has competed in cross-country skiing; he skied the 90 km (56 mi) Swedish Vasaloppet, the oldest cross-country ski race in the world, in 2012, 2013, 2014, and 2015. In 2016, he completed the 54 kilometres (34 mi) Norwegian Birkebeinerrennet with Norway's Crown Prince Haakon. Also in 2016, Frederik completed the 160 km (99 mi) Arctic Circle Race in Sisimiut, Greenland.
On 9 October 2009, Crown Prince Frederik was elected a member of the International Olympic Committee, replacing former Danish member Kaj Holm, who had reached the age of retirement. The Crown Prince's candidature was met with some skepticism in Denmark, as it would mean that the Crown Prince would be on a semi-political committee along with several people who are suspected or even convicted of criminal acts. Another concern was whether or not the Crown Prince's loyalty would be towards his country and government, as the Danish constitution prescribes, or with the International Olympic Committee, as is sworn upon election to the committee. The Crown Prince was given special observer status in National Olympic Committee and Sports Confederation of Denmark, as a way to allow him to work, without having political power.
Frederik announced that his point of focus and reason for joining the International Olympic Committee is to promote an active lifestyle among youth. He was elected for an eight-year term, and made it clear that he would terminate his membership upon ascending the Danish throne.
In 2012, Frederik carried the Olympic flame through Notting Hill, a neighbourhood in West London.
In 2016, Frederik faced criticism for voting against Danish Minister for Culture Bertel Haarder and a majority in the Danish Parliament's wishes on the subject of whether or not Russia should be allowed to compete at the 2016 Summer Olympics following allegations of state-sponsored doping.
On 19 June 2017, the Crown Prince announced that he would continue another term of 8 years. However, in 2021, Frederik was announced that he would step down as an active member of the International Olympic Committee at the committee's annual session prior to the 2020 Summer Olympics, citing a wish to intensify his everyday work as the reason for stepping down in the middle of his term.
In celebration of his 50th birthday, on 21 May 2018, Frederik initiated a public running event across five cities in Denmark called Royal Run with more than 70,000 participants, including himself and his own family. The event was generally deemed as "exceeding expectations" by the public.
The event has since become annual, and was continued in 2019, 2021, 2022, and 2023. The 2020 edition was cancelled due to the COVID-19 situation in Denmark. The 2024 edition took place on 20 May in Copenhagen/Frederiksberg, Kalundborg, Fredericia, Aarhus, and Brønderslev. The 2025 edition took place on 9 June 2025.
