Skyrunner World Series 2026 Kicks Off

This coming weekend (February 20-22, 2026) the Skyrunner World Series kicks off its 2026 racing season in Cuatro Refugios, Argentina. The Carrera 4Refugios is billed as ‘South America’s most technical race’ and offers six distances with varying levels of difficulty:

The 4Ref Nonstop, with 40 km and 3,350 meters of accumulated positive elevation gain, is one of the races with the highest technical difficulty in all of South America.

The terrain traversed is purely characteristic of mountains, with less than 10% of conventional low-difficulty trails, and the vast majority is on High Mountain terrain.

Rocks of various sizes, stream beds and sand; all unstable surfaces with slopes of up to 35° both uphill and downhill.

So as Kilian wonders if “trail running might get too soft and safe” he might look at skyrunning as the solution to that problem.

The mandatory equipment for this race includes a helmet in case you’re thinking that they are just overselling their event.

Watch this hype reel to get a feel for the races, and maybe start looking at airline tickets for next year.
