TT2M begins in Montmédy, a village in the Meuse department of Grand Est, close to the French border. This nature-trail event takes place in early October, featuring trail races and a distinct walking choice. The current schedule provides three single-loop distances: 12 km, 13 km, and 30 km.
The 30 km Trail Grande Boucle is the primary event, featuring 650 metres of elevation gain, making it the more challenging race. The 12 km Trail Petite Boucle includes 250 metres of climbing, and the 13 km route is designated for walkers. Previous editions have also featured a longer 38 km trail with 900 metres of elevation gain, indicating a preference for hilly, off-road courses over flat road races.
