Experienced 80-170km ultra runners who already know what to expect on flowing and technically demanding high alpine trails and what an ultramarathon demands of the body and mind.
The K110 is the ultimate challenge for experienced trail runners: covering over 100 kilometers and around 5,500 meters of elevation gain, the route leads through breathtaking alpine landscapes around Innsbruck. From picturesque valleys to spectacular peaks, runners experience the full diversity of the Tyrolean mountains.
A beautiful loop around Innsbruck, past the Kalkkögel mountains and over the Patscherkofel. The permanently challenging trails should not be underestimated and must be taken into account when considering the distance. Anyone who wants to run here definitely needs to know what they are doing. On the route of the 2023 World Championships, it is now your turn to prove your endurance.

Further Information
Crewing is only permitted at the official aid stations. Please note that not all stations are accessible by car or have parking facilities.
At this distance, you have the option of dropping off a drop bag.
A drop bag is a bag, sack, or pouch in which K110 and K85 participants can store equipment such as new shoes, a change of clothes, or food. We will take your drop bag to a supply station about halfway through the total distance (you will find detailed information about the location of your drop bag in the runner information, which you will receive by email during the event week). After the race, we will bring the drop bags back to the event site, where you can pick up your drop bag again. Please allow some time for this, as we can only return the drop bags after all runners have passed the aid station. Please also note that the mandatory equipment items must still be carried with you.
There will be a mandatory race briefing for all participants of the K15 to K110 competitions.
Here you will receive all the latest information about the course, weather, safety rules, and organizational procedures—compact, clear, and right before the start.
Along the route, you will find aid stations offering a variety of refreshments. You can find more detailed information here.
