There are normally races every week in the big cities around Mexico. For a fuller list of races, check out Araiz Corre’s running blog. For more races in Oaxaca see the Oaxaca Runners Calendar. Emocion Deportiva and En Tus Marcas can also be useful for finding bigger races. Facebook groups such as Puebla Runners and Oaxaca Runners are normally best for finding locally organized events.
For running in Asia and around China check out the Asia race calendar on the Shanghai running website. Shanghai running also host their own races in Shanghai, as do RunnersHai.
