NYRR Run Clean

"Competition is a core tenet of New York Road Runners’ mission to help and inspire people through running. From racing for a top position to striving for a personal best, it’s the journey to the finish line that defines the athlete. To compete fairly and with respect for yourself and others is where it all starts."
-Peter Ciaccia
President, Events, NYRR and Race Director, TCS New York City Marathon

The NYRR Run Clean initiative celebrates the union of competition and individual achievement while working to ensure that runners compete in a healthy and fair environment. Through education, testing, and advocacy, the NYRR Run Clean initiative is committed to fostering a healthy environment for runners to compete on a level playing field.

NYRR is a leader in the global clean sport movement. Since 2002, NYRR has partnered with the United States Anti-Doping Agency (USADA) to test the professional athlete fields at NYRR events. Today, through continued testing for performance-enhancing drugs, counseling with athletes, and a zero-tolerance policy, NYRR is working toward the day when everyone will run clean.

  • Since 2002, in-competition testing has been conducted on hundreds of athletes and wheelchair athletes at more than 65 NYRR events, including the past 13 New York City Marathons. Out-of-competition testing is also frequently carried out by USADA at NYRR events.
  • Since 2012, NYRR has partnered with the IAAF and USADA on a robust out-of-competition (pre-race) testing program at the TCS New York City Marathon, gathering data for the biological passport program. Through this partnership, hundreds of samples have been collected.
  • Athletes who have been suspended by a governing body for using performance-enhancing drugs are not eligible to participate in NYRR races. Appeals are reviewed by the NYRR Race Director.
  • Through the Abbott World Marathon Majors elite athlete testing pool, NYRR helps to fund and manage an unprecedented large-scale out-of-competition testing program of the top marathon runners from around the world. Additionally, the Abbott World Marathon Majors broke ground with a championship payment program that pays prize money out over five years to de-incentivize cheating.
  • Recognizing that those most responsible for a clean sport are the athletes themselves, NYRR has partnered with USADA to present a mandatory series of clean sport educational sessions for athletes who compete at NYRR events.
  • In 2017, NYRR broke ground again. In partnership with USADA, and in addition to the existing professional event testing program, NYRR began testing top finishers at randomly selected non-professional NYRR events.
