Katie, who works at Milbourn Equine, is now preparing with her horse Templar Justice, or TJ for short, to take part in what is widely acknowledged to be one of the world's most difficult equestrian events.
Last year, she competed at the Burghley Horse Trials and was voted "Amateur Rider of the Year" by Horse and Hound magazine.
Katie says she is determined to build on that success with a strong showing at Badminton: "The Burghley Horse Trials were amazing last year. I was so excited to be there and it went so well. To now be competing at Badminton will be an awesome experience.
"It’s one of only six 'five-star' equestrian events in the world and to compete there really is my dream come true."
