Rue de la Haie, 76230 Bois-Guillaume, France
The event titled "Semi-marathon et 10 km de Bois-Guillaume" is a town-organised road running meeting held in Bois‑Guillaume, Normandy, France. It is organised by the Ville de Bois‑Guillaume (Service des sports) and traditionally offers two distances on the same day: a half‑marathon (21.0975 km) and a 10 km race. The event is measured by the FFA and is limited to a total field (cumulé) of around 1,300 participants according to official information; start and finish are located on Rue de la Haie in Bois‑Guillaume.
The course mixes urban streets and forested sections (including parts near Houppeville and the Forêt Verte of Mont Saint Aignan) and the half‑marathon is run as two loops of roughly 10 km each. The 10 km is described as convivial and accessible to beginners and to runners with disabilities, and the race has a local character with close proximity to Rouen. Exact 2026 race pages note the edition date and start arrangements may be published separately by the organiser.
