The attendance is worth for different reasons – the sporting adventure, the experience of nature and culture, the healthy climate, last but not least the après-marathon. It will be run on well-kept forest trails across a calm and romantic forest-, meadow- and pond countryside, only in the local area on tarmac. Experience pure nature and at the same time a fascinating cultural landscape. In ponds accumulated water was the power source for the water wheels of the mines of the Upper Harz Mountains (Oberharz). This unique water management system has been acknowledged as world heritage.
Before you go
Racing it
Trail-Ready Shoes
The course runs on well-kept forest trails through meadows and ponds, with asphalt only in the local area. Wear trail shoes or road shoes with grip for packed natural surfaces.

Cool Start, Warm Effort
Typical race-day temperature is 13.9°C. September in the Harz can feel chilly before the start; use layers you can shed once you warm up on the trails.

Pond and Mining Heritage

Stay for Après

Getting Around
Hahnenklee is a compact spa village in the Harz, so race-day roads will be busy and parking limited. Walk or arrive early, and expect local traffic diversions.
Spectator Spots
Spectators can gather in the village center near the stave church and spa park, then walk to nearby pond and forest edges where the course passes.
Recover and Explore
Recover with an easy walk to the stave church or along the quiet Harz trails. The town's cool climate and mining-water heritage make lingering outdoors pleasant.
