Semi Marathon de Bullion

About this event

The Semi Marathon de Bullion takes runners through the scenic Vallée de Chevreuse, just southwest of Paris. This February road race offers a single half-marathon distance, winding through the charming communes around Cernay-la-Ville. The course typically features a mix of forest roads and quiet village streets, with rolling terrain that provides a proper challenge without being overly mountainous. It's a solid choice for road runners looking to kick off their season with a race that balances accessibility with genuine hills. The winter timing means cool temperatures and potentially dramatic skies over the valley's historic abbeys and châteaux.
