On September 20 , 2025, the ARC Foundation is organizing the twelfth edition of its triathlon to markPink October. The Triathlon des Roses is a 200m swim, 6.7km bike ride and 4km run, starting at La Faisanderie, the Stade Français' private stadium, and finishing at Domaine National de Saint-Cloud ! The aim is to raise as much money as possible in support of breast cancer research, and to raise awareness of the benefits of sport in a race for the common good.
Accessible to all women who engage in regular, moderate physical activity, this triathlon can be completed individually or in relay teams of 2 or 3, and is now also open to men, in team format only (cycling reserved for women)! You'll need one person to swim, one to pedal and one to run. Please note: to take part in the race, participants need to raise 300 euros for individuals and 500 euros for relays. Enough to rally your friends and family around this worthy cause!
As a reminder, 59,000 cases of breast cancer are recorded every year, and 9 out of 10 cases can be cured. 96 projects - that's the number of breast cancer research projects funded by the ARC Foundation between 2020 and 2024, for a total of 14.4 million euros.
