Legend
Once upon a time, in a land shrouded in mist and steeped in ancient secrets, castles and fortresses stood like silent guardians upon the hills. Some said they had been enchanted by the ancestors; others believed that the stones themselves held the stories of those who had once been brave enough to pass through their gates.
One night, when the moon stood high in the sky and the stars whispered, a mysterious call rang out: Those who follow the Ruf der alten Mauern will not only solve the riddles of the ancient stones, but also find glory and honour. Yet only those who understand the signs along the paths will be able to discover all the castles and fortresses and reach the long-awaited destination.
You have now been chosen to answer this call. Before the first light of day, you will receive the secret coordinates that will lead you to each castle and fortress. It is up to you to plan your route, overcome obstacles and uncover the secrets hidden within these ancient walls.
In the end, you will return to the place where it all began – the heart of the legend. There, you will be celebrated not merely as a seeker, but as a hero. Every step, every castle and every fortress will be recorded by a GPS tracker, allowing the world to follow your journey.
And so, Katjas Laufzeit now awaits all those brave enough to answer the Ruf der alten Mauern Take on the route, explore the castles, solve the riddles and become part of this legend.

NEW: Der große Ruf der alten Mauern – 100 Miles
For everyone who feels that the challenges so far are not enough, 2027 brings a very special challenge:
Approx. 100 miles – 160.9 kilometres.
The 100-mile event starts on Friday, 24 September 2027 at 6:30 pm.
You have a total of 36 hours, until Sunday, 26 September 2027 at 6:30 am, to complete the challenge.
The 100 miles are divided into four stages of 25 miles each.
For each stage, you will receive two sets of coordinates. You must visit these locations before returning to the start/finish venue.
And here’s the special part: You decide the order in which you complete the four stages.
You can start with Stage 1, begin with Stage 4, or choose your own order. However, the four cut-off times are the same for all participants. They are based solely on the common start time of the 100-mile event.
The Four Cut-Off Times
1st cut-off:
Saturday, 25 September 2027, 3:30 am

By the first cut-off, you must have completed one stage. By the second cut-off, two stages must be completed. By the third cut-off, three stages must be completed. And by the fourth and final cut-off, all four stages must be completed.
For example, if you start with Stage 4, your first cut-off is still at 3:30 am. If you start with Stage 3, the same 3:30 am cut-off applies.
After completing each stage, you return to the start/finish venue. There, you can refuel and recharge at our aid station before heading out on your next stage.
The clock keeps running the entire time.
