Fast, Flat & Windy

May 2025

111 km Around Sylt
Single & 2-/3-person relay


A tour around Germany’s most beautiful island!

Experience all facets of Sylt in an ultra-marathon in one day, from sunrise to sunset.

Your opponents? Only you, the wind, and the weather.

Unparalleled moments await you: Through the nature reserve around Germany’s northernmost point at Ellenbogen, along the Wadden Sea, accompanied by the tides, through the ports of List and Hörnum, Sylt life in Keitum, solitary moments at Morsum Cliff and Rantum Basin, and the bustling life in Westerland. All in one race.

And the best part: Start and finish in Kampen, the Mecca for nature lovers and jet-setters alike. Be ready for these special Sylt moments!

With 14 refreshment points where the communities and Sylt businesses present themselves, you’ll be well taken care of.

The flat course invites you to pick up the pace, but be careful: Even a stiff breeze can sometimes feel like 1,000 meters in elevation.

The North Sea Ultra Marathon is a UTMB® World Series Index Race.
