From a Group of Friends to the World’s Largest Running Community

What started as a small crew training for a 50-mile race in NYC has grown into one of the most connected running communities in the world.

How It Started

It All Began With a Run Through NYC

In 2022, a small group of friends came together to train for a 50-mile race. What started as casual long runs in the city quickly turned into something bigger. More runners started showing up, week after week. The energy was contagious.

Soon, our group runs weren’t just training sessions—they were where friendships were formed, goals were set, and the idea of Endorphins was born.

How It Grew

More Cities. More Runners. More Energy

Word spread via social media. More runners joined. What started as a local NYC crew expanded to Boston, Philly, Chicago, LA, Austin, and beyond.

  • We now host 1,500+ free group runs each year.
  • Our community has grown to 25,000+ runners worldwide.
  • We’ve built a training platform, performance apparel line, and race-day experiences designed for runners at every level.
