SLO12RUN in Kranj (4/6/2023) in 2023 received the Silver label of the International Association of Ultrarunners (IAU) for 12 hour run and Bronze Label for 6 Hour Run.
In 2008, the IAU decided to introduce race marking to ensure that the track was measured in accordance with international regulations, which is especially important when competing at global or European level. The match must also has to be recognized by the National Athletics Federation (the Athletic Association of Slovenia).
The IAU only officially recognizes appearances in competitions marked IAU.
We are very proud of the silver and bronze label, as this makes the match internationally valid.
