20th Anniversary Evening Extravaganza
with Gillian Higgins and Simon Grieve
An unmissable evening, 20 years in the making
Thursday 25th June 2026
Onley Grounds Equestrian Complex, Willoughby, Rugby CV23 8AJ
To mark two decades of Horses Inside Out, we've brought together something extraordinary. Fresh from his sensational performance at the 2026 Badminton Horse Trials, 5-star event rider Simon Grieve joins Gillian for an evening that will completely transform how you think about riding and training your horse.
Simon rides on the flat and over jumps, giving you a ringside view of elite equestrian sport through the lens of anatomy and biomechanics. You won't see this anywhere else.
“Becoming a great horseman isn’t just about being a good rider,” explains Simon. “It’s about knowing your horse inside out! It’s about knowing what makes them tick as well as how their body works. I want to learn more about how my horse’s body works, to help me become that better horseman.”
Join Simon and Gillian for an interactive demonstration. Discover how to ensure your horse’s comfort, create a willing and happy horse as well as improve your riding and training. Come to observe, question and absorb as Simon’s top horses Buster and Miracle are put through their paces and we ask the why and how questions!
Meet the Hosts
Gillian Higgins
Gillian has spent 20 years helping riders of all levels understand equine anatomy and biomechanics. Her ability to connect complex science to everyday training is unrivalled.
In this demonstration you’ll see first hand how having this knowledge can be applied to your own horse, whatever you do with them.
Simon Grieve
One of Britain's most respected and popular eventers, Simon has competed at 20 five-star events, including jumping double clear and coming 18th at Burghley 2025, a five-star debut for him and his horse Buster.
He also completed Badminton 2026. Simon is bringing two very different horses and a wealth of insight into training for performance at the very highest level.
What to Expect on the Night
Three stunning horses, including Simon's 5* horse Buster, and 3* horse Miracle. Both will be painted to reveal skeleton and musculature in vivid detail, will perform live in front of you. Watch them on the flat, doing pole work, in-hand exercises and jumping to see exactly how training choices affect movement, comfort and long-term soundness.
Simon and Gillian will discuss training methods and philosophy together, a rare and fascinating conversation between a world-class competitor and a leading equine anatomist, covering everything from posture and collection to how to keep your horse performing at its best for years to come.
Approved CPD with Pony Club, BHS, BD and RDA.
