Barbaro romped to a six-and-a-half-length win last year – the biggest winning margin for more than 60 years.
However, the horse broke his leg in the Preakness Stakes and was put down in January.
Now Yum! Brands – presenting sponsor and parent of brands such as Pizza Hut, KFC and Taco Bell – says if the win is emulated $1m will be equally shared between the winning trainer, owner, jockey and the Barbaro Memorial Fund.
