Samantha Osborne Kornetto

Samantha Osborne
British Showjumping and HOYS Showing

I am an amateur, North Yorkshire based horse owner and rider. British Showjumping is my passion and focus but in previous years I have competed in the show ring. I was fortunate enough to qualify a range of horses for RIHS and HOYS, and I also judged at numerous shows as a panel judge for various societies.

I have gained experience and knowledge from working for several professional yards in a range of disciplines. Since becoming a secondary school teacher 14 years ago, I have completed additional equestrian qualifications, such as Level 5 Equine Behavioural Science, as I value learning.

Furthermore, after winning the TSM BETA International Amateur Rider Award in 2014, I decided to explore equestrian media by writing freelance for national equestrian magazines, working as a micro influencer and being part of The Equestrian Business Awards judging process. I enjoy breaking horses in, retraining racehorses and supporting other riders to achieve their goals. 

I am thrilled to be selected as a Synovium ambassador for the year ahead. KWPN gelding, Kornetto, purchased by Becky Matthewman, joined me this month and with veterinary advice and top quality scientifically developed healthcare, Kornetto will have the best backing to begin his BS journey.

I am so excited to share his results using Agility this summer. Earlier this season, I produced Leyward Diamond Jubilee and began her showjumping education at British Novice level. She qualified for the second rounds as well as Star of the North in her first sixth months.

This year, Aimee has qualified 2 ponies for the Winter JC Championship where she finsihed in 8th. Aimee also gained the ride on Leo VII who is a very exciting prospect! She told us “I am aiming to jump him in the Foxhunter Second Rounds and the Junior Trials next year. My pony, Wots Up Dot, whom I feed the gastrosafe supplement due to ulcers, stepped up to jump the European Pony Trials and she also qualified for the Leading Pony Showjumper of the Year Final where she came 9th”

“Zoverla stepped up to jump my first 1m40 Junior European Trial where she came 3rd out of a strong field of horses and riders. She also qualified and came 9th in the Silver League Final at Aintree. I feed Zoverla the Agility supplement and she has felt amazing since starting it.”

“I feed Synovium supplements to my horses and I am very impressed with the difference it has made. In particular, my horse Quintus WZ, who was difficult to keep in top condition due to ulcers. Since feeding him the Gastrosafe and the prefit supplements, you can see a marked improvement to his condition and he recently got all his Newcomers double clears ready for next year. I’m very excited to be working with Synovium and having their support with my horses.”
