Overview

• Diagnosed in autumn 2023 with a gastrointestinal stromal tumour, Dalin withdrew from the Transat Jacques Vabre before returning to competition under medical supervision.
• He kept the illness private during the solo round‑the‑world race, took daily immunotherapy, adapted sleep and diet, and set a race record of 64 days.
• He underwent surgery in February after finishing, says his condition is currently stable, has lost significant weight, and considers the next Vendée Globe out of reach for now.
• In comments reported by L'Equipe, he said the tumour was removed in February but recurred elsewhere in April, and he remains under treatment.
• La Force du destin, co‑written with journalist Didier Ravon and published by Gallimard on Thursday, frames the disclosure as his campaign continues in his absence with Sam Goodchild and with sponsor support, with project plans expected to be outlined on October 13.
