Semi-Marathon and 11 Km of the Croix Verte

Semi-Marathon Et 11Km De La Croix Verte is a local road and forest race held in Montsoult, Île-de-France, with the 2026 edition scheduled for 14 June 2026. The meeting comprises two distances: an 11 km race and a half marathon (listed at 21 km / 21 000 m on the official calendar). Both courses run through the roads and woodland paths of the neighbouring communes, offering a slightly hilly, mixed-surface route that combines village streets and forest tracks. The event is presented on the Fédération Française d'Athlétisme calendar and uses the TimePulse platform for entries.

The races are organised by USMBM-CP and aimed at regional participants, with entries handled online via TimePulse and on-site bib collection details published by the organiser. The half marathon includes mid-race refreshments (two aid stations are listed) and the organiser notes rewards for finishers. This departmental-level meeting emphasises local club organisation, accessible distances and a community race-day experience rather than elite championship status.
