USA Track & Field (USATF) is the United States national governing body for the sports of track and field, cross country running, road running and racewalking (known as the sport of athletics outside the US). The USATF was known between 1979 and 1992 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 until the Amateur Sports Act of 1978 dissolved its responsibility. Based in Indianapolis, USATF is a non-profit organization with a membership of nearly 130,000. The organization has three key leadership positions: CEO Max Siegel.; Board of Directors Chair Steve Miller, and elected President Vin Lananna. USA Track & Field is involved in many aspects of the sport at the local, national, and international level – providing the rules, officials, coaching education, sports science and athlete development, youth programs, masters (age 40+) competition, the National Track & Field Hall of Fame, and an annual meeting. It also organizes the annual USA Outdoor Track and Field Championships. Through its sanctioning program, the national body provides the insurance coverage necessary for members to rent facilities, thus allowing for competitive opportunities for all athletes to happen.
