L’Oritrail begins in Sorèze, a commune in the Tarn, directing runners onto the Montagne Noire trails. It is a trail-running event, with Desperado Trail organizing and November editions noted in the event materials.
The routes traverse the wooded, hilly terrain above Sorèze, featuring a climb towards the Canal du Midi sources. Course options are updated for new editions, so the race utilizes local trail features rather than a single, unchanging city circuit.
