The South Tyrol Ultra Skyrace, an Alpine extreme mountain race, requires exceptional physical and mental fitness. Athletes can choose from four different routes of varying degrees of difficulty. All four routes run along the so-called Horseshoe Circuit in the Sarntal Alps.
This extremely demanding trail run is 121 kilometres long and involves a total difference in altitude of 7,554 metres. The "Ultra Skyracers" have 40 hours to run from Bolzano to the Latzfons Cross, the Penser Joch and the Obere Scharte. At the end of the race, they run past the ‘Rocky Men’, (Stoanernen Mandln) and return to Bolzano.
The South Tyrol Skyrace, on the other hand, has the second longest route at 69 kilometres, followed by the third longest one, the "Südtirol Sky Marathon", which is 42 kilometres long. The shortest, but still not to be underestimated, "Südtirol Sky Trail" is 27 kilometres long.
