Dirty Dozen 50k
Queens County, United States • 23 Aug 2025
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.
