The Course de Brassioux begins and ends at the Brassioux gymnasium in Déols, central France. This is a small nature-running series offering three options: a 6 km race, a 12 km race, and a 6 km canicross for runners accompanied by dogs. The races take place in April; the two foot races start simultaneously, with the canicross departing shortly after. Registration is open to participants from the cadet age category and older.
Most of the course follows paths, distinguishing it from a typical town-center 10K and aligning it more with a local trail race. FENARAC 36 is the organizer, and this marks the event's 27th edition. Previous editions also utilized nature routes ranging from approximately 6 km to longer distances, indicating a local event developed around the Brassioux paths rather than a set road circuit.
