Holger Rune's comeback remains uncertain as he continues his rehabilitation from Achilles surgery without a confirmed return date. The former world No. 4 has been out of competition for almost nine months since the injury suffered at the Stockholm Open.
What happened?
Rune is currently training in Monaco, where extreme heat conditions have added physical strain to an already demanding workload. His schedule now includes full court sessions, gym work and recovery blocks distributed across full training days.
The Danish player has avoided setting a fixed return date, but says he is now fully free of injury and focused entirely on rebuilding match fitness for the ATP Tour. Rune described his recovery as entering its final performance phase, where the emphasis has shifted almost entirely to explosive movement, sprint mechanics and full court coverage.
Why it matters for Holger Rune
Rune confirmed that he is already playing long, match-style sessions, but stressed that this is still part of a controlled build-up rather than a return to competition. The knee is feeling great, the Achilles is feeling great, he said, emphasizing that the injury itself is no longer a limitation.
He explained that the next phase of his preparation is focused on explosive movement patterns and court coverage at full speed. Rune has recently trained with top-ranked opposition, including Jannik Sinner and Grigor Dimitrov, as part of his return to high-level hitting.
What comes next?
Rune's daily workload has increased significantly, combining on-court tennis, physical conditioning and structured recovery across full-day training schedules. The emphasis is on gradually increasing intensity while maintaining control of fatigue and physical load.
Despite the progress, Rune reiterated that no official timeline has been set for his return to the ATP Tour. We're working a lot on plyometrics, the final sprinting, the last explosive movements in the corners, he said, highlighting the importance of movement quality at maximum intensity.
Rune's support team in Qatar will continue to play a crucial role in determining his return date. The Danish player will have to wait a bit longer before making his comeback, as his medical team advises him to take more time to get ready.
