Holger Vitus Nødskov Rune was born on April 29th, 2003, in Gentofte, Denmark to mother Aneke Rune and father Anders Nødskov. The Dane started playing tennis at the age of six, following his sister's footsteps.
Since his early childhood, Rune has been coached by Lars Christensen, even though he was often tied with renowned coach Patrick Mouratoglou during his early playing days on the ATP Tour.
After starting to train at the Mouratoglou Academy in 2016, Rune won the European U14 singles championship in 2017, and two years later, the Danish player defeated Toby Alex Kodat to win the 2019 Roland Garros Boys' singles trophy.
Aged only 16 years, one month and 18 days, Rune played his first ATP Challenger match in Blois, which he also managed to win, beating Colombia's Nicolas Barrientos Gallo. Still in his junior days, the Dane rose to the world no. 1 spot after beating fellow junior rival Harold Mayot in the ITF Junior Finals.
Rune got to experience how it feels like to play against the best players in the world, when he served as a practice partner at the 2019 ATP Finals. In his early career days, he was also often seen practicing with Serbia's Novak Djokovic.
At the 2021 Argentina Open, Rune made his ATP debut, and he soon started climbing the ranks. His first Grand Slam tournament was the 2021 US Open, but he lost the first-round match to Novak Djokovic.
A first-round exit awaited him also at the 2022 Australian Open, but at the French Open in the same year, he managed to reach the quarterfinals. Soon after that, his biggest career success followed when Rune defeated Novak Djokovic in the 2022 Paris Masters final to win his first ATP Masters 1000 title.
Already in 2023, Rune completed his first full year on the ATP Tour, in which he directly qualified for all tournaments, and he managed to be consistent, climbing to the Top 5 in the ATP Rankings and reaching the Monte-Carlo Masters and Italian Open finals.
