French ocean racer Charlie Dalin has revealed that he was diagnosed with cancer in 2023, and completed – and won – the gruelling 2024/25 Vendée Globe while continuing treatment for the illness.

Dalin, skipper of the IMOCA Macif Santé Prévoyance had withdrawn from the 2023 Transat Jacques Vabre transatlantic race for unspecified medical issues. He confirmed in his autobiography La Force du Destin (‘The Force of Destiny’), released tomorrow, that he was in fact diagnosed with a gastrointestinal stromal tumour that autumn.

Despite this, Dalin went on to qualify for the Vendée Globe, completing the Transat CIC and return New York Vendée-Les Sables Race in the summer of 2024.

Dalin then delivered one of the most impressive winning performances in the solo non-stop around the world Vendée Globe race’s history, pushing his IMOCA to blistering speeds and maintaining a ferociously relentless work rate throughout – famously riding a low pressure system in the South Indian Ocean to pull ahead of his close rival Yoann Richomme on Paprec Arkéa.

He finished the race in 64 days, 19 hours, 22 minutes, and 49 seconds, demolishing the previous course record by 10 days.

Charlie Dalin cancer diagnosis

Dalin reports that he first noticed symptoms in late 2023 during a training sail, and received his diagnosis after emergency scans.

The skipper, who sails for MerConcept, did not publicly announce that he was going through cancer treatment, though he and his team adapted his training due to the weight loss and fatigue he suffered.

Dalin was first to finish in the previous 2020/21 Vendée Globe, but fellow competitor Yannick Bestaven was awarded the race win following receiving time in redress for his part in the search and rescue of Kevin Escoffier, whose boat PRB broke up off South Africa.

Before the 2024 race Dalin had spoken about how he came to terms with the unique emotional rollercoaster of crossing his first ever Vendée Globe in first place, but knowing his victory wouldn’t last.

Dalin’s 2024 Vendée Globe

With a purpose built Verdier-designed IMOCA and – outwardly at least – apparently perfect preparation until the 2023 Transat Jacques Vabre, Dalin was a hot favourite for the 2024 Vendée Globe.

But privately, his participation was in doubt until the last minute, when a scan in November 2024 confirmed that his tumour had not grown and he was able to join the record-sized fleet on the start line in Les Sables d’Olonne. During the race he managed the illness with daily medication, and prioritised rest when possible.

“I stuck to my strategy, sleeping an average of six and half hours per 24 hours, which is more than on my first Vendée,” he told French news agency AFP, in one of several interviews ahead of Thursday’s publication of his book.

“I had stomach pains, but I just told myself: you don’t have time to worry about that. The pains went away as quickly as they had come,” he added. “By the time I got back to shore, I had almost forgotten about them.”

Speaking about his race post-diagnosis, Dalin revealed that he felt very relaxed during his second Vendée.

“On November 10, 2024, the day of the Vendée Globe start, I was incredibly relaxed. We often hear that taking part in the Vendée is already a victory. In my case, that was exactly it! Because a year earlier, I didn’t even know if I would survive,” he told French sailing magazine Voiles et Voiliers.

“In fact, during a chat during the trip up the Atlantic, when I was neck and neck with Yoann (Richomme), I said: ‘In the end, it’s just a game.’

“Many people thought it was a bluff, thinking it didn’t correspond to my usual state of mind. But no, I was really relaxed, happy to be on my boat, battling for the final victory.”

Incredible story

Dalin had considered going public with his diagnosis during the media frenzy after winning the Vendée Globe, but when offered a book deal decided that would be the better way to tell his story.

“Frankly, if a screenwriter had imagined a script around the Vendée, he would never have dared to write the story of a sailor with cancer, who returns to the race of his dreams and wins it after crossing the line first, but finishes second in his first participation…

He would have been told that it was too much, that it didn’t make sense. And yet, that’s exactly what happened,” Dalin told Voiles et Voiliers.

Dalin’s recovery

Shortly after the finish in February this year, Charlie Dalin underwent surgery and is now focusing on his recovery. “I had a tumour 15 centimetres long on my intestine. They removed it in February, but it came back elsewhere in April,” he explained to French newspaper L’Equipe.

British skipper Sam Goodchild is racing Macif in next month’s Transat Café L’or (formerly the Transat Jacques Vabre), with new IMOCA co-skipper Loïs Berrehar. The Macif team will be making a further announcement about their sailing squad later this month.

All of us at Yachting World sincerely wish Charlie and his family the very best for the future. Charlie and his team generously gave me the opportunity to sail aboard his incredible Macif in September 2024, and it was an absolute privilege to witness him at the helm. We hope to see him back there very soon.
