From March 10 to 22, 2026, turn your energy into a donation to support medical research and innovation at the Curie Institute. As part of the national campaign “Une Jonquille Contre le Cancer” (A Daffodil Against Cancer), the connected challenge of the “Course de la Jonquille Contre le Cancer” (Daffodil Race Against Cancer) allows everyone to run as many kilometers as possible against cancer at their own pace. The “Course Jonquille” app counts the kilometers covered by participants in France and abroad. For every kilometer covered, €1 is donated to the Curie Institute by the event's main partner and by the companies involved in the challenge! Whatever pace you choose, walking and running will increase your individual and overall kilometer count, whether you participate solo or as part of a team. In order for your sporting activities to be counted, the app will ask for permission to access your Apple Health data.
