Tour & Trail des Commères is a late-October trail running and walking series in Sirod, in France's Jura region. It provides several single-loop options: the 23 km Trail des Chamois climbs about 1000 m, the 11 km Tour des Commères is the most popular trail race, and the 6.5 km Tour de la Percée is shorter. Walkers can choose from 6 km, 11 km, and 15 km routes, and separate courses are available for children and juniors.
The routes traverse forest paths and trails in the upper Ain valley, with some segments following the historical traces of Alésia. A shorter promotional route passes the old gabelle toll gate at Château Villain; the organiser describes it as easy yet technical. The event originated from the long-running Tour des Commères, with a trail format introduced for its 30th edition. It maintains a local, multi-distance feel, with club runners, walkers, families, children, and record-chasers participating together.
