Buena Vista, the 2010 Japan Racing Association Horse of the Year, and Victoire Pisa are to compete at the Dubai World Cup, the world's richest horse race, on March 26, the JRA said Friday.

Buena Vista won two Grade 1 races last year — the Victoria Mile in May and the Tenno-sho in October. Victoire Pisa beat runaway favorite Buena Vista at the season-ending Arima Kinen in December, adding to the three-year-old's victory at the Satsuki-sho (Japanese 2,000 Guineas) in the spring.

The Dubai World Cup boasts a purse of $10 million with the winner taking the top prize of $6 million.
