Trail Race Partners

We love trail running! So, when it came came for us to share the word about Run the Alps, we wanted to do something that would support the wider trail running community.

The idea is simple: trail races and trail clubs share information about Run the Alps. If someone joins us for a trip, we’ll donate 5% of the cost of that tour to the club or race.

Interested in being a partner? Drop us a note! We’d love to hear from you, and support your efforts to share trail running in your community.
