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.

[3][4] The winner of the first women's race, María del Carmen Cárdenas, later became one of the first female Olympic marathon runners for Mexico.

[5] 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.

[10] The 2020 edition of the race was cancelled due to the coronavirus pandemic, with all registrants given the option of obtaining a full refund or transferring their entry to 2021 or to another runner for 2021.

The final part of the race follows Avenida de los Insurgentes westwards to reach the end-point at Estadio Olímpico Universitario.
