What makes Kauto Star a legendary horse?

With this year's Cheltenham Gold Cup taking place on Friday, BBC Radio 5 live's horse racing team take a look at one of its most famous icons - Kauto Star - and the team behind him.

Trained by Paul Nicholls, the French-bred horse is bidding for a fairytale triumph in the twilight of his career.

In 2009 Kauto Star became the only horse to regain the Gold Cup, having first triumphed two years earlier. He also won a record fifth King George VI Chase at Kempton Park on Boxing Day last year.
