Belinda Stronach is the brains behind Saturday's Pegasus World Cup, which was the world's richest horse race last year -- with a $16 million prize purse.

A former politician, Stronach ran to become leader of the Canada's Conservative Party in 2004. She served as an MP from 2004-2008, switching her allegiance to join the Liberal Party in 2005.

Now she is immersed in the racing industry, running her family's Stronach Group empire. Here she is pictured at the 2016 Breeders' Cup in California with actress and model Emily Ratajkowski.

Arrogate -- named World's Best Racehorse in 2016 -- beat California Chrome in a classic final duel to win the inaugural 2017 Pegasus World Cup, then worth $12 million in total.

Gun Runner, winner of the Breeders' Cup Classic in November 2017, won the second running of the Pegasus World Cup last year.

The 2019 edition will include a new turf-race, which hopes to attract a more international field. The $16 million purse will not be split between the two Grade 1 races.

The Pegasus World Cup combines racing with popular culture. Many top musicians have performed at the event, with Snoop Dog scheduled to headline this year.
