Our global dream team. Built to win.

In 2020, we didn’t just build a team. We built a movement. We searched the globe to welcome the best and brightest talent, and now our OAC global team, made up of a diverse group of middle and long-distance runners, is on a quest to be the best.

The On Athletics Club, or OAC for short, is based at a full-time training facility in Boulder, Colorado. Led by three-time U.S. Olympian and running legend Dathan Ritzenhein, alongside coach Kelsey Quinn, our athletes are training hard ahead of a new season of challenges, world stage events and chasing their dreams.

At OAC, it’s not just about winning – it's about camaraderie, shared pursuit, and the belief that running is better together.
