Randonnee Du Telethon - Merville is a charity cycling and walking day held in Merville, northern France. Sign-on takes place in the morning at Salle Polyvalente Raeckelboom Le Sart. The event is organized by Cyclotourisme Mervillois and typically provides several relaxed route options instead of a single competitive race. Cyclists can select routes of 25, 32, 47, and 62 km, while walkers have shorter options ranging from approximately 6 to 16 km.
The cycling routes are categorized by difficulty. Easier blue routes cover about 18 or 32 km, and a more challenging red route is around 47 km in certain years. The inclusion of walking routes makes the event accessible to individuals seeking a local randonnée without cycling. Entry fees are reasonable, with separate pricing for the general public and club members. The primary purpose of the day is to support the Telethon, with all proceeds from the event being donated to this cause.
