Trail du Bouton d'Or is a late-October trail and nature race held in Ahuy, within the Côte-d'Or department of Bourgogne-Franche-Comté. Participants can select a short 3 km loop, a popular 10 km loop, or a more challenging 23 km loop, accommodating both local beginners and those seeking a longer woodland run.
The 10 km route includes approximately 256–273 m of elevation gain and typically attracts the largest number of participants, with over 300 runners in the previous edition. The 23 km route ascends about 694–761 m and crosses paths through the woods of Ahuy, Hauteville, Etaules, and Darois. The race begins at the sports complex.
