2T2M - Trail Tour du massif Montmorencéen - Montlignon 2027

2T2M is a spring trail-running weekend held at La Mayotte in Montlignon, Val-d'Oise, north of Paris. The races take place in the Forest of Montmorency, a 2,000-hectare state forest featuring steep paths, damp valleys, and high points overlooking the Paris basin. The series offers events from children's runs to an ultra around the Montmorency massif, with distances including approximately 10 km, 14 km, 22 km, 25 km, 42 km, over 60 km, and nearly 80 km. This is a true trail event; the 21.6 km course is 95% trail and climbs 800 m. The 21.6 km race begins at La Mayotte, goes through Saint-Prix, has an aid station at 9 km, and incorporates the sentier des lisieres in its final section. Longer distance participants can opt for a marathon-distance route with around 1,500 m of climbing, 60 km routes with just over 2,000 m, or the main event at almost 80 km with approximately 2,659 m of elevation gain. The weekend also features 2T2M By Night, a night race requiring a headlamp. The event benefits the Mutuelle la Mayotte center, which supports children with disabilities.
