“The truth is that this disease is destroying me and I cannot manage it,” Casey Stoner said in remarks reported in November 2020. The Australian former MotoGP champion was describing his experience with chronic fatigue syndrome (CFS), not offering a clinical explanation of its cause or a prognosis. The latest located update is a February 2026 interview report in which he described a setback after falling ill in late 2025; it does not confirm his health status today.
What Casey Stoner said about living with chronic fatigue
In a November 27, 2020 report, Fox Sports Australia quoted Stoner from an interview with El Mundo. He described months of unexplained deterioration and said he would become exhausted after training. He also explained how he tried to pace himself: “Now I am a little better, I have learned to manage my energies. I start the day at 50 per cent and the energy goes down until I feel empty.”
The “50 per cent” figure was Stoner’s personal description of his energy at the start of a day, not a clinical measurement. His stark phrase about the disease belongs to that same reported account, rather than serving as a medical assessment of what caused his symptoms.
What has been reported about the timeline
| Period | What the source reports | What it establishes |
|---|---|---|
| 2009 | Stoner’s official biography says he had health issues involving Epstein-Barr virus and lactose intolerance and missed races. Casey Stoner’s official biography | An earlier health episode; it should not be treated as the cause of his later CFS account. |
| 2018 | A 2022 retrospective says Stoner reported his CFS symptoms began in 2018. Crash.net’s 2022 retrospective | A symptom-onset date attributed to his reported account, not an independently documented diagnosis date. |
| November 2020 | Fox Sports Australia reported his remarks to El Mundo about exhaustion, deteriorating health and learning to manage his energy. Fox Sports Australia’s report | His public description of symptoms and daily impact at that time. |
| July 2022 | A retrospective attributed to Stoner accounts of difficulty getting out of bed, being sofa-bound for months, conserving energy, exhaustion and difficulty thinking. Crash.net’s 2022 retrospective | Reported personal experiences, not a clinical record or general medical guidance. |
| Late 2025, reported February 2026 | Stoner told Crash.net that after a Europe trip he caught a virus and was sent “back into some chronic fatigue again.” He said he had stepped away from bikes for the time being. Crash.net’s February 2026 report | His account of a setback and his hopes for riding more in 2026; it does not verify his condition after the interview. |
What the 2026 update does—and does not—say
In a report published February 17, 2026, Crash.net quoted Stoner describing a late-2025 setback after a virus following a trip to Europe. He said: “Then all of a sudden, got back from Europe, got a virus, and it sent me back into some chronic fatigue again.” He also said he had taken a back seat from bikes and hoped to move in a better direction and enjoy riding more in 2026.
#1 Best Overall
This is a reported account of what he told the outlet. It does not establish that the virus caused his underlying condition, describe a medical evaluation, or confirm whether his symptoms improved after the interview.
Stoner’s racing career and the separate 2009 health episode
Stoner is an Australian former MotoGP racer and two-time world champion. His official biography records championships with Ducati in 2007 and Honda in 2012, 45 Grand Prix victories, and retirement at the end of the 2012 season. The biography also notes the health issues and missed races in 2009 involving Epstein-Barr virus and lactose intolerance. That earlier episode is distinct from his later public account of chronic fatigue syndrome; the available reporting does not establish a connection between them.
Rank #2
What is not established about his condition
The public remarks and biographical material describe Stoner’s reported symptoms and the effect on his daily life. They do not identify a clinician, document the diagnostic process, establish a clinical cause, or provide an evidence-based treatment plan or prognosis for him. His reported virus-related setback should not be turned into a proven explanation, and no cause should be inferred from his racing career or the 2009 episode.
