Goûter en Or 2026, in Paris and Across France : A Nationwide Mobilization Against Childhood Cancer !

For the past ten years, every September has been an opportunity for children and adults alike to rally in support of pediatric cancer research and help provide new treatment options and hope for young patients and their families. This year, the Grand Goûter en Or, organized by Gustave Roussy with the support of the Jardin d’Acclimatation, will offer a full day of festive activities from 10 a.m. to 6 p.m. on Sunday, September 13, 2026.
 

Families will be able to enjoy a day of solidarity and entertainment, including wooden games, face painting, balloon sculpting, magic shows and stilt walkers. The Vaillante Show & Marching Band will energize the event with three performances throughout the day, while Pierre de Maere will join attendees in support of the cause. The day will also feature an exceptional live performance by Skip the Use at 4:30 p.m. In addition, 1,000 free solidarity snacks will be distributed to children at 4 p.m.

Across France, the campaign extends well beyond Paris through a network of local partners, including municipalities, childhood support associations and local businesses. Together, they organize solidarity events close to families, such as community snack gatherings, fun walks, cooking workshops, cinema screenings and charity lottery events.

More information about Goûter en Or and the programme of local initiatives is available on the Gustave Roussy website.

Whatever the initiative, the goal remains the same: 100% of the funds raised are entirely dedicated to research into childhood and adolescent cancers.

Each year in France, approximately 2,300 children and adolescents are diagnosed with cancer. Thanks to major advances in research, the five-year survival rate now exceeds 80–85%. However, for young patients who still do not benefit from sufficiently effective treatments, the fight continues.

As the leading comprehensive cancer center in France and Europe, Gustave Roussy plays a major role in pediatric oncology research. Its researchers work to develop new therapies, improve understanding of childhood tumors and deliver innovative treatment options, particularly for cancers that remain difficult to cure.

By supporting Goûter en Or, participants contribute directly to funding research programmes dedicated to improving outcomes and developing new therapeutic solutions for children and adolescents affected by cancer.
