La Pont’Oise is a free semi-nocturnal trail event in Pont-Sainte-Maxence, located in France’s Oise department. Participants can select from 8 km, 15 km, or 25 km routes. The 25 km option includes a 600-metre climb, presenting a genuine trail challenge distinct from a flat evening run.
The City of Pont-Sainte-Maxence organizes this race, now in its 11th edition. Younger participants have adapted distances of 600 m and 1.2 km. The main event offers timing, aid stations, parking, a cloakroom, and registration via Adeorun.
