We are proud to announce the opening of season 2023.

The AATC league represents the connection and cooperation of the 10 most vibrant races from Italy, Poland, Slovenia, Croatia, Bosnia, and Herzegovina. They are all inspired by genuine human values – connecting with nature, being part of local communities, contributing to a better world, and being free and authentic. All this with high organizing standards, outstanding landscapes, and positive vibes.

With the new year, we proudly open the AATC season 2023.
