On June 1st we will open the registrations for the Barcelona Trail Races with a great desire to return to offer you a great race.

As you know, the new Parc Natural de Collserola regulations forced us to reduce the different circuits that we had until now to only one, of 76 km. You can participate in Gran Trail Collserola (GTC) of 76 km, or, and for those who like the shortest distances, in Gran Trail Collserola X2 (GTCX2).

This 2017 we decided to create a relay race, the GTCx2. During the relay race, two runners will take one turn each. The place where first runner will make the pass to second runner is the refreshment post at El Papiol. Relay race runners will have to reach El Papiol or return from El Papiol to finish line by their own means. The first relay will be of 47 km and the second one of 29 km.

The total number of bib-numbers is 500 (runners of GTC + teams for relay race GTCx2 = 500). The registration will open at the same time.
