The Gran Premio Nacional, or Argentine Derby,[1] is a Group 1 flat horse race in Argentina open to three-year-olds run over a distance of 2,500 metres (1.6 mi) at Hipódromo Argentino de Palermo.
[2] The Gran Premio Nacional has been run at Hipódromo Argentino de Palermo annually since 1884.
[1] By 1923, the year the Uruguayan entry Sisley won, the purse was worth $40,000.
[3] In 1933, the favorite Hasta Hoy was attacked by masked men the night before the race.
Hasta Hoy was left unable to run, leaving Requiebro and Támesis to dead heat for first in a field of ten, the smallest in the race up to that point.
