USA Track & Field (aka USATF) is the national governing body for the sport of track and field (or 'athletics') in the United States. The USATF was known for a number of years as The Athletics Congress (TAC) after its spin off from the Amateur Athletic Union (AAU), which governed the sport in the US through most of the 20th century.
Based in Indianapolis, Indiana, USATF is a non-profit organization with a membership of nearly 100,000. The organization is led by President Bill Roe and CEO Craig Masback. USA Track & Field is involved in many aspects of the sport at the local, national, and international level - coaching education, sports science and athlete development, youth programs, masters track and field (age 40+) competition, the National Track & Field Hall of Fame, and an annual meeting.
