The Mexico City Marathon (Spanish: Maratón Internacional de la Ciudad de México) is an annual road running event over the marathon distance 42.19 kilometres (26.22 mi) which is held on the streets of Mexico City in late August or early September that in 2018 received IAAF Gold Label Status.
The race was established in 1983 at a time of growing interest in marathons in the country – the Independencia Marathon had been launched three years earlier and the Monterrey Marathon had been run over the full distance in 1982. The winner of the first women’s race, María del Carmen Cárdenas, later became one of the first female Olympic marathon runners for Mexico. The competition was mostly national in nature until the turn of the 21st century, when more elite international runners began to compete, and win, at the race. Eileen Claugus of the United States was the first foreign winner in 1987, and Ethiopia’s Tesfaye Tafa became the first male foreign winner two years later. Since 2002 only one Mexican man has won the race, and no Mexican woman has won since 2010.
