The Asterix – UTVV 15 km route runs from Ajdovščina towards the medieval monastic village of Vipavski Križ, which represents the ascent of the walled hill as the only ascent on the route. Runners circle inside the walls and go through the southern gate towards the river Vipava. The route then runs along the river on hardened macadam paths until it reaches the longest trails crossing the Vipava via the Napoleon bridge in the village of Dolenje. The route ends in Ajdovščina. An easy, playful distance of less than 200 VM, suitable for all beginners in trail running.

The UTVV ultramarathon challenge is set in the valley where one of the most important battles of the late Roman period, The Battle of the Frigidus, also called the Battle of the Frigid River, took place in 394. The battle was fought between 5 and 6 September 394 between the army of the Eastern Emperor Theodosius I and the army of the Western Roman ruler Eugenius. With Theodosius’ victory, the Roman Empire was united under one emperor for the last time in history. Also, the victory of Theodosius brought the final religious dominance of Christianity in Europe.
