About this race

The 4rd Annual NYC Stair Set of Doom Ultra isn’t your average race, it’s an adventure through the heart of New York City, where every mile tells a story and every staircase is a challenge. Covering 33+ miles across city streets, parks, and dirt trails, this race gives you a raw, unfiltered experience of the city’s most iconic spots and hidden gems. From historic bridges to winding park paths, you’ll get a tour of NYC like no other.

Here's what you’re up against:

  • 3,500+ feet of elevation that will push your legs to the limit
  • 33 miles through neighborhoods most races never touch
  • 90 stair sets (some massive, some tiny) scattered throughout the course
  • 16 parks where the city’s greenery meets your grit
  • 6 bridges crossing boroughs and bringing you new challenges
  • 4 boroughs to show you the full range of what NYC has to offer

This race is as real as it gets. While we’ll have an aid stations along the way, the Stair Set of Doom is unsanctioned and largely self-supported, meaning you should rely on your own water, fuel and restroom usage (public restrooms will be marked along the route). It’s a grind, but for those who want to experience NYC in the most epic way possible, it’s the ultimate test.

The course map and route instructions will be shared once you register for the event.

What's Included:

  1. An Epic day
  2. Finisher Tee Shirts
  3. A 1st Place Price

There will be a post race beers at the Broadstone Bar and Kitchen. 

Join us on this Epic adventure!
