The Royal Run of Saint-Germain-en-Laye

La Foulée Royale de Saint-Germain-en-Laye is a one-day community running event held on the esplanade of the parc du château de Saint-Germain-en-Laye that showcases the historic château terrace and adjoining forest. The event programmes multiple distances for a wide range of participants, including a 1.5 km youth race, 5 km and 10 km "Nature" courses and a 5 km Nordic walking option, and it highlights scenic routes through formal gardens, parkland and woodland. Organisers emphasise easy public-transport access via RER A and a finish at the foot of the château, making the setting a central part of the race experience.

The event offers practical participant services including guarded bib/bag collection and a souvenir for every finisher, with timing handled by a professional timing provider. The 10 km is noted as counting toward the local Yvelines challenge, and a short prize/ceremony is scheduled as part of the day’s programme. Entrants can register via the official event site or the event timing/registration pages, and a volunteer programme and group registration option are also provided.
