Mutant_
Mutant_ started in Seoul in 2017 when jk.beak founded the crew under the name SMIT, meaning Single Mutant Infects Totality. The goal was infectious and clear: spread the running virus. Now led by GANZ, Mutant_ holds around 25 members who operate on a simple philosophy: everyone is the main character. Each person shoots their own color against the background of black. Running here is just the beginning, a launchpad for something bigger. On Mondays and Thursdays at 8pm, the crew gathers at Banpo Bridge on the Han River, one of Seoul's most iconic spots, ready to run with passion, creativity, and an energy that makes everyone feel seen.
