Les Marinières en Rose is a Pink October charity aquathlon held in Villefranche-sur-Mer, on the French Riviera, featuring swimming and running. The event raises money for breast-cancer care, with all funds collected going to the Centre Hospitalier Princesse Grace de Monaco.
The race began modestly, with its first edition attracting 68 participants who started in heavy rain. The broader event incorporates women-focused racing under the Aquathlon Féminin Les Marinières en Rose title, while the listed youth race is mixed gender and designated as Aquathlon S Jeunes. It operates as a distinct local event, separate from any larger challenge series.
