Téléthon du BTP Paris is a charity run and walk in Paris, scheduled for late November. It supports research into rare diseases, and the format is open: participants can run or walk at their own pace rather than treat it as a strict race.
The main route is a 1 km road course in the city, also marked as the most popular distance. The event is built around solidarity and draws people connected to the building and construction world, along with anyone who wants a short, accessible way to support the cause.
