Trail de la Foulerie is a trail race held in early October in Chaumont-en-Vexin, a village in France’s Oise department, located about an hour by public transport from Paris. The town hall organizes this annual event, which connects running with Pink October, the breast-cancer awareness campaign.
The route follows local paths around Chaumont-en-Vexin and the Oise countryside. The terrain features numerous twists underfoot, prompting a warning for runners to mind their ankles. The event's atmosphere is local and lighthearted rather than polished: participants are invited to display their most stylish running shoes, wear pink, set aside the workweek, and run to support those in need.
