Overview
- Diagnosed in autumn 2023 with a gastrointestinal stromal tumour, Dalin withdrew from the Transat Jacques Vabre to begin treatment.
- He took daily immunotherapy during the 2024–2025 Vendée Globe, adjusted sleep and diet on board, and set a record time of about 64 days.
- After finishing in January, he underwent surgery in February and later told L’Equipe the tumour reappeared elsewhere in April.
- He says he has lost significant weight and is currently unable to race offshore, ruling out the next Vendée Globe while hoping to return in shorter transatlantic events.
- His account appears in La Force du destin, published Thursday by Gallimard, which he frames as a message of hope for others facing serious illness.
