The Baltic Sea island of Bornholm between Denmark and Sweden is a vacation paradise – and home to what is probably the toughest trail run in the country – the Hammer Trail Bornholm. The supreme distance is 82 picturesque and quite technical kilometers with over 3,000 meters of elevation gain. We were there for the 15th anniversary.

Trail running legend Kilian Jornet set up his foundation to protect our mountains and their nature. We asked him about his goals and measures.

The Kilian Jornet Foundation not only bears the most illustrious name in trailrunning – Kilian Jornet – but is also one of the most prominent voices when it comes to bringing sustainability to the mountains and trails. One of its central tools is the Green Trail concept. A collaboration with the legendary Zegama-Aizkorri race shall take it t from the concept phase to practical application. We discussed what this means exactly.
