Perun Skymarathon is a 41-kilometer mountain race held in the Moravian-Silesian Beskids of the Czech Republic, specifically within the Silesian Beskids region known locally as Goralli. The event begins and concludes at the parking lot by Flight Park in Oldřichovice u Třince, designed as a challenging skymarathon rather than a road race.
The course encircles the mountain massifs of Javorový, Ropice, Prislop, Kozinec, and Ostrý, passing near several peaks between 900 and 1,000 meters in elevation. Participants are divided into basic age groups: women under and over 40, and men under and over 40.
