Conquer the slag heaps of the UNESCO World Heritage Mining Basin
The Trail des Pyramides Noires is a nature running event organized every year in May by the Mission Bassin Minier, starting from the historic 9-9bis site in Oignies. Created in 2014, this iconic trail offers distances from 10 to 115 km across the slag heaps of the Nord-Pas-de-Calais Mining Basin, a UNESCO World Heritage site. Runners tackle spectacular landscapes shaped by mining history, between black pyramids, rider paths, and reclaimed natural spaces. A children's race (1.5 km) and a Nordic walk complete the offering.
Since 2014, the Trail des Pyramides Noires (TPN) has become one of the most emblematic sporting events in the Hauts-de-France region. Organized by the Mission Bassin Minier, it invites runners to discover and conquer the slag heaps, these artificial hills inherited from three centuries of coal mining. The setting is unique: the routes cross a territory inscribed as a UNESCO World Heritage site since 2012, where nature has reclaimed former industrial sites.
The TPN offers a range of distances suitable for all types of runners:
The slag heaps offer surprising elevation changes for a region known to be flat. The climbs are short but steep, the descents are technical on black shale, and the rider paths—former mining railways—connect the different sites. Runners pass through historically significant places: the slag heap of Loos-en-Gohelle (the highest in Europe), the Base 11/19, the 9-9bis site where coal was discovered in 1842, and many other heritage sites.
The Trail des Pyramides Noires is more than just a race: it is a tool for promoting the territory. The event helps to change perceptions of the Mining Basin, showcasing the beauty of these transformed landscapes and the richness of their biodiversity. The Mission Bassin Minier, a public institution created in 2000, leads this project as part of its mission for the renewal of the mining territory.
Beyond the competition, the TPN fosters a spirit of solidarity and conviviality. The finish at the 9-9bis site turns into a real celebration with generous refreshments, musical entertainment, and a partner village. The 2025 edition, the tenth, marked a symbolic milestone with over 5,000 participants, confirming the TPN as the largest trail race in Northern France.
