K24 - Carinthian Mountain Challenge
K24 connects five Carinthian peaks in the toughest mountain endurance test.
Ultra Trail
K24 is the most demanding Carinthian mountain challenge, connecting five of the most important peaks from Črna na Koroškem – Uršlja gora, Smrekovec, Raduha, Olševa, and Peca. The approximately 80-kilometer-long route, with over 10,000 meters of ascent and descent, is a true test of endurance, perseverance, and mountain spirit. Anyone who completes it in less than 24 hours becomes a member of the prestigious K24 club.
Conditions
The K24 route is based on mountain ethics and trust. Hikers must reach all designated points and record their own time, without special supervision. This makes the challenge even more personal – it's not just about kilometers and elevation gain, but also about honesty, perseverance, and a responsible attitude towards the mountains.
K24 is a demanding challenge that, in addition to good physical fitness, requires experience, careful planning, and respect for nature. The journey combines effort, solitude, breathtaking views, and contact with the most beautiful corners of the Carinthian mountains.
