Dirty Dozen 50k

Dirty Dozen 50K

The Dirty Dozen 50K takes place on August 29, 2026 in Forest Park, Queens, New York. The event uses the Orange Trail and is presented as a looped course that remains inside the park.

The course is a 2.5 mile loop run counterclockwise and repeated 12 times to total the 50K distance. Each loop includes about 300 feet of elevation, producing a substantial cumulative climb over the full race. The route passes through shaded woods, rolling terrain, and quieter park pockets within city limits.

Aid stations are positioned so runners pass a fully stocked station after every lap; these stations provide hydration and nutrition and are staffed by volunteers. The event is described as having a grassroots, no-frills atmosphere that blends competitive racing with community support. There is an 8 hour cutoff for completing the course.

Practical details note that registration is open but space is limited and that registration closes on August 26. There is bib pickup and a race briefing before the start. The park is reachable by public transportation or car. Late August weather may include heat, humidity, or rain, and trail shoes are recommended.

The race is organized by a team of New York based ultrarunners who focus on grassroots, accessible events within the five boroughs. Visit the organization's website for the most recent information.
