The Maratona refers to a 138Km route with 4230 meters of ascent culminating in the Passo Giau (10km with average 10% gradient). There is also a short route and a Medio route. I was pleased to be able to complete the Medio route which incorporated 106km and 3008 metres of ascent, in the knowledge that there was nothing left in the tank. Chapeau (hat tip in cycling parlance) to all the boys and girls that completed the Passo Giau.
