Holger Rune has spent the early months of the 2026 season away from the ATP Tour, continuing rehabilitation after suffering a ruptured Achilles tendon in October 2025. The former world No. 4 sustained the injury during the Stockholm Open semi-finals, an incident that required surgery and forced him into a long recovery period while the season continued without one of the tour’s most prominent young players.

As the BNP Paribas Open unfolds this week at Indian Wells, Rune remains focused on rebuilding his fitness rather than competing. The Dane, who reached the final in Tennis Paradise in 2025, has been sharing updates from his rehabilitation and says he is encouraged by the steady progress he has made in recent months.

His recovery has taken place largely in Doha at Aspetar, a specialised sports medicine and rehabilitation centre that regularly works with elite athletes across multiple disciplines. The 22-year-old has been working through the final stages of a programme designed to restore strength and mobility in the injured tendon.

Despite the extended absence, Rune insists his ambitions remain unchanged. The Dane, who has slipped to world No. 25 this week—his lowest ranking since October 2022—has acknowledged that his eventual return will likely require rebuilding momentum on the tour.

Rune’s current rehabilitation phase focuses on restoring explosive movement, a key requirement for a player whose game depends heavily on aggressive baseline exchanges and rapid changes of direction. The final stages of recovery are typically among the most demanding following Achilles surgery, particularly for athletes competing at the highest level.

“My rehabilitation is progressing very well,” he said during an interview with So Tennis. “I’m currently focusing on explosive movements, the final step before I can move more freely again on a tennis court. I’m optimistic and motivated because I see improvements every day.”

The decision to complete rehabilitation in Doha reflects the importance placed on specialised treatment for this type of injury, which has historically proven difficult for athletes who rely on speed and explosive movement.

“Aspetar is one of the largest sports medicine and rehabilitation centres in the world, specialised in Achilles tendon recovery,” the 2022 Paris Masters champion added. “They work with many high-level athletes from different disciplines and have cutting-edge medical expertise, technology and performance specialists. For an injury like this, it’s essential to be surrounded by the best professionals to avoid any mistakes.”

Rune’s absence has also provided time for reflection after a career that accelerated quickly following his breakthrough on the ATP Tour. The Dane captured the Paris Masters title in 2022 and established himself as one of the leading players of his generation, reaching three other Masters 1000 finals and making several quarter-final appearances at Grand Slam tournaments.

“My goal is to come back stronger and wiser,” said the 22-year-old Dane. “And I can’t wait to feel the support of the fans on court again. I miss it a lot. Injuries are difficult, but they also help you put things into perspective.”

Away from the weekly intensity of the tour, Rune has also emphasised the importance of maintaining balance during the recovery process, particularly when dealing with the mental challenges that often accompany long-term injuries. “Yes, I think mental health is extremely important in high-level sport. For me it’s about maintaining balance, staying close to my family, surrounding myself with the right people and having clear goals. But we shouldn’t forget that pressure is a privilege.”

Following the tour from afar has also allowed Rune to observe the ongoing debate surrounding the ATP calendar. The expansion of several Masters 1000 events to two-week formats has intensified discussion among players about scheduling pressure and recovery time during long stretches of the season. “The calendar is very dense. I think the challenge is to find the right balance so that players can give their best in front of the fans. I don’t have a miracle solution.”

For now, however, Rune’s priority remains the final phase of rehabilitation before gradually reintroducing tennis-specific movement on court. “The next steps are to gradually intensify my work with more demanding exercises and eventually return to tennis with controlled movements on the court.”

“That return is planned soon," the former world No. 4 added. "Everything depends on how my body responds at each stage, so we are proceeding step by step. My goal is not to rush things but to come back as quickly and as safely as possible.”

For the moment—with no confirmed date for his return—everything suggests that the recovery process has been positive for the Dane. Early speculation even suggested he could miss the entire 2026 season, but preliminary reports now indicate a possible return around the middle of the year, with the objective of appearing at Roland Garros at the end of May—roughly seven months after the injury.
