Les Côtes de la Châtaigneraie begins at Place du Fort in Cardaillac, a village in the Lot department of southwest France. It is a race day featuring several formats: a 26 km trail, a 14 km trail, a 10 km road race, and Nordic walks of 10 km and 6 km. This event is in its 43rd edition, placing it among the established local French running events.
The program offers runners a choice between trail distance and road speed, with walkers having their own shorter Nordic walking options. The 10 km and 14 km races include an inter-company challenge and a CDR 46 challenge, intended to attract workplace teams and local departmental runners alongside regular participants. Entry fees are modest and vary by distance, with walks at the lowest price and the 26 km trail at the highest. On-site registration incurs an extra fee for runners, but walkers are exempt. Grand Figeac and the Lot department are listed as partners, connecting the event to the local area around Cardaillac.
