Marathon on the Rocks

11 Sept 2021

Born(holm) for trail running

Run along the coastal cliffs of Denmark’s best kept secret!

Marathon on the Rocks is a splendid but challenging coastal trail run on the northern part of Bornholm.

The race features both a marathon and a half marathon.

Bornholm is a Danish Island known as the pearl of the Baltic Sea. Also known as the Sunshine Island or the Rocky Island, Bornholm is an intriguing combination of forest, coastal cliffs and small beaches, with a twist of Medieval castle ruins and small fishing towns with harbors and smokehouses. 

The entire route will take place on small biking tracks, forest trails and the rescue paths close to the coastline from the start in Gudhjem, around Hammershus to the finish line in Skovly, just north of Rønne.

It's no surprise that Bornholm has been voted as Europe's second best island in 2019 (Conde Nast). To truly appreciate the enchanting atmosphere this island has to offer, one must be ready to adapt to their laid-back island lifestyle.
