About

The race

The Boulogne-Billancourt Half Marathon is an annual road running event over the half marathon distance which takes place in November in Boulogne-Billancourt, France. This National level race accommodates several thousand marathoners every year. The course for the race is a looped circuit that starts and finishes at the town hall. It follows a clockwise route along the river Seine, passing the Sèvres – Cité de la céramique, Pont de Saint-Cloud. It heads north towards the Longchamp Race course and has a short loop through the Bois de Boulogne, where it reaches the halfway mark. At this point the course loops back on itself and follows the Seine in a southerly direction until it finally ends up at the town hall finish point.

Pro tips

Racing it

    Loop start and finish

    The race starts and finishes at the town hall, so you can leave warm clothes at the start area and don't need transport to the start.

    Cold November race
