More than just trail running
Yttersia Trail Running Weekends are about much more than kilometers and elevation gain.
They are about standing on a mountain ridge above the fjords of Senja, sharing stories with like-minded people around the dinner table, recovering in the sauna after a long day in the mountains and experiencing Northern Norway through the eyes of a local.
Whether you are preparing for your next mountain race or simply looking for an unforgettable adventure, this weekend offers a unique combination of spectacular trail running, local knowledge and genuine community.
With a maximum of eight participants, every weekend remains personal, flexible and adapted to the group.
Come for the trails. Stay for the experience.
We look forward to welcoming you to Yttersia Base.
