What to Expect on GranDiagonal
With 17 years of experience organizing cycling events in Portugal, our team has strived to design a route that offers all ultracyclists and bikepackers the best way to cross Portugal from its northwest to its southeast.
From Caminha, on the western Atlantic coast, to Vila Real de Stº António, on the southern Atlantic coast, GRANDIAGONAL® by EVOC takes all cyclists to some of the most important landscapes of one of the oldest countries in the world, traveling along secondary roads with little traffic and unique landscapes.
From conquering the high mountains to exploring the vast plains, the great diversity of landscapes, cultures, and environments is one of the hallmarks of this journey.
More than a great challenge, GRANDIAGONAL® by EVOC is a deep dive into the soul of a country that always has something special to surprise us.
