Daffodil Race

Daffodil Race is a Chrome extension page for a charity running campaign that turns your miles into donations for cancer research at the Curie Institute. From March 10–22, 2026, participate in the national Une Jonquille Contre le Cancer campaign and the Course de la Jonquille Contre le Cancer, running at your own pace solo or with a team.

The app tracks kilometers covered in France and abroad, with €1 donated for each kilometer by the event's main partner and participating companies. Whether you walk or run, your effort boosts the overall donation total. To count activities, the app will request permission to access your Apple Health data.
