Diligence, professionalism, drive, support of the municipality Kranj, Slovenian Athletic Federation and all other sponsors, volunteers, runners and other partners of the event are one of the main reasons for the growth and development of the 12 hour run in Kranj (SLO12RUN).
All of the above, including the city itself, should be justifiably proud that the race is recognized as one of the top organized ultra races. Currently, there are only a couple of ultra races in Europe that can boast a gold label. In 2021, we received a silver label, and three years later we can proudly boast of the highest award, the gold label of the IAU.

Each level of the labelling requires a lot of responsibility and the fulfillment of strict requirements. Getting the gold label is even more challenging. Because we strive for perfection and excellence, after three years we obtained the IAU gold label, which we are extremely proud of.
We invite you to save the date, June 2, 2024, and join us.
We will open applications on Monday, 11th of September 2023!
