"Thank you Stardust," writes Sienna Charles on her social media. "For the past six years, you have been a true gift to our family. With Harry, you won the World Cup in London and some of the biggest classes in the world."

"After that, you became a mentor to me. A loyal partner who gave me my first five-star experience, where we jumped a clear Grand Prix and finished second in the Nations Cup. I will never forget our experiences! It was a privilege to be your rider!"

With this, the British rider officially announced the mare's retirement from sport.

We wish Stardust a happy retirement!
