Welcome letter

Collserola has been and continues to be our playground. Running in these paths is a privilege for those who live in Barcelona city, but it is also a privilege for all those who come to participate in the race from abroad.

From the Barcelona Trail Races we continue working to offer an affordable ultra trail running race, without no other pretension that to prove yourself, either in its solo version, or in its version by relays.

Year after year we want to continue insisting on the importance of protecting and preserving this park, is our obligation, the same way it is a right to enjoy it. And we cannot let them take the right away.

Respect the mountain, run and enjoy it
