Fixed route for the whole year of 36Km with 1940m D + born in 2015 thanks to the contribution of Piacenza Sport and the Bobbio Track & Trail association. The race is developed entirely in Val Trebbia touching also the municipalities of Marsaglia and Coli. The scenarios of the bends of the river Trebbia are something unique. Even the non-competitive 14Km route that follows the competitive route for a while is spectacular with the passage to the Carlone Falls. The departure and arrival in the Abbey of San Colombano give a historical touch to the event, you can admire the cloisters and the arrival in the corridor under the arcade is something exciting. Arriving a day in advance you can visit the various museums and stroll through the narrow streets of the ancient village of Bobbio. From 2018 to the trail event is connected the short route that follows the first 16km of the classic race with arrival in Marsaglia.
