White Run

On February 21, the gates of the Kőbánya cellar system open once again – but this time you step into a world where darkness and light dance an eternal waltz. In the black depths, every movement begins to glow, and the UV-white reflections bouncing off the walls guide your path. Are you ready to shine bright enough to run through this mysterious underground labyrinth?

At the 2026 Underground Run, everything revolves around light: snow-white outfits, glowing LEDs, blazing UV signs, and mysteriously vibrating light corridors. It feels like stepping into an elegant, secret underground ball – where the rhythm is set by your footsteps and the scenery is drawn around you by bursts of light emerging from the darkness. In the cold tunnels, the purity, freshness, and elegance of white become your shield against the shadows.

This is not just a run. It’s an adventure dressed in light, an elegant underground madness where party meets challenge.
You run in white – but it’s your light that colors the way. Are you ready to shine underground?
