Dirty Dozen 50k

The Dirty Dozen 50K is a challenging ultramarathon held in New York City, featuring a 50-kilometer distance composed of 12 hilly loops in Forest Park. Known as one of the tougher ultra-races in the city, it tests both physical endurance and mental toughness. The course's repetitive loop format and elevation changes make it a unique and demanding event for runners seeking a serious challenge.

The race fosters a gritty, determined atmosphere for participants aiming to conquer the "Dirty Dozen" mission. Registration closes shortly before the event, which takes place annually in late August. Visit the organization's website for the most recent information.
