Grande Trail da Serra d'Arga takes place in Dem, Caminha, Portugal. There are 5 other trail races within 250 km, shown on the map, if you want to combine them in one trip.

Grande Trail da Serra d'Arga has 5 distances: 15K, 17K, 31K, 50K, and 100K. The longest is the 100K.

No: Grande Trail da Serra d'Arga is an independent race, not part of a circuit such as the UTMB World Series or the Golden Trail Series.

For the 100K, plan around 24 weeks of specific training if you already run regularly. For the 15K, about 8 weeks are enough. Build up long runs with climbing and add two short strength sessions a week.

It is a technical mountain race: expect rocky trails and steep descents, so train on similar terrain.

For its technical terrain, choose shoes with deep lugs and good protection and enough cushioning for the distance. Good options: Hoka Mafate 5, Nike ACG Zegama Trail, and Altra Olympus 7. You will find them, and the rest of the gear, in “How to prepare” below.
