Where did Casper Ruud grow up?

Casper Ruud grew up in Oslo, Norway, the capital city of Norway, where he was born on December 22, 1998, into a tennis family, and later spent significant time training in other locations. He is the son of Christian Ruud, a former professional tennis player who was Norway's top player in the 1990s and reached a career high ranking, and his mother Lele Ruud. Casper grew up in the Snarøya area near Oslo, in a family that had a tennis court background, and he started playing tennis at a young age coached by his father Christian. As a junior, he trained in Oslo and later moved to train at the Rafael Nadal Academy in Mallorca, Spain, which is run by Rafael Nadal, to develop his clay court game, as Norway has limited clay courts and cold winters. He also spent time training in other locations for junior development. So Casper Ruud grew up in Oslo, Norway, specifically in the Snarøya suburb, in a tennis family, with early training in Norway and later advanced training at the Rafa Nadal Academy in Mallorca, Spain, which helped him become Norway's most successful male tennis player.
