Trail des Hautes Falaises is a trail running race in Sassetot-le-Mauconduit, Seine-Maritime, Normandy, near the high cliffs of the French coast. It takes place in late September, set within the straightforward, off-road domain of trail running: timed races on natural terrain, distinct from road races through urban areas.
The primary listed option is a 20 km single-loop course with approximately 300 metres of elevation gain, identified in the race details as the distance that unites participants. The event connects with coastal and natural themes, emphasizing running near the Normandy coast on a manageable course suitable for a wide range of trail runners, rather than speed on paved surfaces.
