The TM (Trail do Marão) is the 40km distance within the annual UTM Ultra Trail do Marão event held each March in Amarante, northern Portugal. Running point-to-point from Pelourinho, Teixeira (Baião) to Parque do Ribeirinho, Amarante, the course covers 40km with 2,500m of elevation gain through the Serra do Marão mountain range. It opens with a punishing 7.1km climb to the Seixinhos summit at 1,100m — 724m of gain in the first sector alone — before descending to Mafómedes, one of the most isolated mountain villages in Portugal.
The course crosses 3 mountains and the Aboboreira range, passing through the largest megalithic necropolis in northern Portugal and a waterfall corridor along the Ribeiro da Goiva, then finishes along the River Tâmega into Amarante. Entry for the 2026 edition was €65 (€1.63/km). Porto Airport (OPO) is 42 minutes away by road. With a 10-hour time limit and 2 ITRA points, the TM suits experienced mountain runners comfortable with prolonged steep hiking and technical mountain terrain.
