A Community Walks for Hope: The Olivia Association’s Fight Against Pediatric Cancer
Nearly 200 people braved the wind on Sunday, March 29, 2026, to participate in the inaugural solidarity walk organized by the Olivia Association. The event served as a powerful demonstration of support for research into a rare and currently incurable pediatric cancer.
From Personal Tragedy to Collective Action
The walk began at the Jardins de la Fontaine in Nîmes, France, winding through the city’s landmarks – Cours Jean-Jaurès, the arenas, and the Maison Carrée – covering a three-kilometer route accessible to all. The driving force behind this mobilization is Larissa Gaillard, whose nine-year-old daughter, Olivia, passed away on February 29, 2024, after battling an aggressive form of brain cancer called a gliome infiltrant du tronc cérébral.
“We wanted to create the Olivia Association and organize this solidarity walk to aid research, so that children can have hope and not experience the tragedy we went through,” shared Larissa Gaillard.
A Rare and Devastating Disease
Approximately 50 children in France are diagnosed each year with this specific type of brain cancer, which affects a vital area of the brain making surgical intervention impossible. Radiotherapy remains the only standard treatment, but it doesn’t guarantee a cure. The Olivia Association is directing 100% of donations to a dedicated research program at Gustave-Roussy Hospital in Paris, the only institution currently focused on this cancer, supported by a team of fifteen researchers.
Beyond the Walk: Future Initiatives
This walk marks the first initiative for the association, with plans already underway for future fundraising events. These include an online lottery, a race in Béziers, and a choir performance in Nîmes later in the year. The outpouring of support has been remarkable.
“We are pleasantly surprised. People are here, touched by the cause,” Larissa Gaillard noted. Social media has too played a role, with Olivia’s sister, Joanna, mobilizing support online, stating, “I walk for my sister and for all sick children.”
The Power of Community in the Face of Loss
The event highlighted the importance of community support for families facing pediatric cancer. As one participant, Alexandre, expressed, “No family should go through this alone.”
