The Semi-Marathon et 10 km de la Durance is a road race held in November in Charleval-en-Provence, located in the Bouches-du-Rhône department of southern France. Participants can select either a 21.1 km half marathon or a 10 km race. Both are promoted as fast courses, with the 10 km specifically designed for those aiming for a personal best. Participation is limited to 1,100 runners, making it a select event rather than a large-scale city race.
The course traces the Durance riverbanks through a Provençal landscape of open fields, garrigue, and olive groves, with mountains visible in the distance. The half marathon is presented as the more challenging performance option, while the undulating 10 km offers a shorter distance with potential for record-breaking times. As a relatively new event, its primary appeal lies in straightforward, fast road running in rural Provence, under the gentle November sun, with a smaller field than typically seen at major mass participation races.
