Who is tested?

NYRR conducts random post-race testing of top finishers at our invitational races: the TCS New York City Marathon, United Airlines NYC Half, UAE Healthy Kidney 10K, NYRR New York Mini 10K, and New Balance 5th Avenue Mile. In  2017 we also introduced random post-race testing of top finishers at additional races throughout our schedule of events. More details will continue to be provided.
