Trail Tour du Massif Montmorencéen 2027

The Trail Tour du Massif Montmorencéen, or 2T2M, takes runners into the Montmorency forest from Montlignon in Val-d’Oise, north of Paris. Held in late April, it offers distances from a 10 km introductory run to an 80 km ultra. This event suits local runners testing trail conditions and ultrarunners seeking a long day. The climbing is a notable feature for the Île-de-France region: approximately 450 m of gain on the 10 km, 900-980 m on the 20-23 km races, around 2,000 m on the 40-45 km distances, and over 2,500 m on the 60-80 km courses. The routes are not considered highly technical, but runners encounter genuine elevation, forest paths, and sufficient variety to make the massif seem more extensive than its proximity to Paris might suggest. Recent participants commend the course marking, organization, aid stations, and the post-race meal. One runner described it as the most scenic trail in Île-de-France. The race typically includes short, medium, and ultra distances, with specific lengths around 10.6 km, 23.1 km, 44.9 km, 62.5 km, and 83.9 km, allowing participants to choose between a swift forest run and a substantial mountain-like challenge near the capital.
