Subway parkour, also known as metro running or train surfing, is a risky and exciting sport that involves navigating through underground subway systems in urban areas. Participants use their agility, speed, and quick reflexes to jump over obstacles, run along train tracks, and perform daring stunts while avoiding security guards and oncoming trains. This high-adrenaline activity has gained popularity in recent years, despite its dangers and the illegality of trespassing on subway property. With its mix of athleticism, danger, and thrill-seeking behavior, subway parkour provides an adrenaline rush for those brave enough to partake in this extreme sport.
