The Berkshire course is holding a showcase from the British Equestrian Federation, showcasing different ranges of sport horses.
Eventer Laura Collett, who has been working with Kauto Star, will also be providing a jumping masterclass along with the expert coach Yogi Breisner.
Collett received the celebrated chaser and dual Gold Cup winner before Christmas when his owner Clive Smith decided he should do something different.
“He’s in great form and very happy,” said Collett, who is based at the Membury Estate in Wiltshire.
“We’re quite restricted with space in the parade ring, as they have been quite wet there and we’ve got to really stick to the outside.
“We’ll be keeping it fairly simple, with walking and cantering, and hopefully he can show a few transitions (changing the way he moves).
“The main thing is that it will be nice for everybody to get the chance to see what he’s doing now.”
Kauto Star made his British debut at Newbury in December 2004, when he won a novice chase, and scraped home on his only other visit to the Berkshire circuit, when warming up for his first Gold Cup success in 2007.
