The Marathon Relais Inter-Entreprises is a 42.195 km road relay in La Pommeraye, a village in Calvados, Normandy. It typically takes place in mid-September, with the marathon distance divided among team members rather than run by a single participant. The format is designed for workplaces, allowing employees to compete together under their company banner, with a limit of four teams per company.
The event prioritizes participation from local businesses, associations, employees, and the general public over elite marathon performance. A recent running saw over 200 teams and 1,200 participants, making baton exchanges and team strategy key elements of the day. The race originated from the older French marathon championship tradition, but its distinct character is local and functional: it offers visibility to nearby companies, connects the corporate sector with volunteer organizations, and transforms a full marathon into a collective endeavor.
