Rando des Terrils Oignies 2026

The 45km Oignies Slag Heaps mountain bike ride includes the Bois de l'Emolière forest, the slag heaps of Carvin, Oignies, and Ostricourt, and numerous forest singletracks, such as the one at the Thumeries Golf Course. Another excellent edition on a well-known but always enjoyable course, especially when the sun is shining, the signage is perfect, and the aid stations are well-stocked.
