History
In 1942, Tonico won the Gran Premio Miguel Alfredo Martínez de Hoz in a walkover.

The Gran Premio Miguel Alfredo Martínez de Hoz was run as a Group 2 race from 1989 to 2000 before being upgraded to Group 1 in 2001, a designation which it has maintained since.

In 2011, the Brazilian racehorse Send inthe Clowns became the first foreign horse to win the race.

Puerto Escondido became the first horse to win the Gran Premio Miguel Alfredo Martínez de Hoz twice since it became a Group 1 race in 2018. He remains the only horse to have done so, as of 2024.
