The award — which is sponsored by equestrian PR agency Tim Smith Marketing — recognises riders who work closely with their sponsors, promoting products through advertising, marketing and PR.
Sophie is sponsored by Staffordshire-based saddlers Black Country Saddles, which nominated her for the award.
“I was absolutely delighted to find out that I had won,” said Sophie.
“Black Country Saddles is a great supporter — its saddles are the very best and help me compete at the highest level in paradressage.”
Mark Bryan of Black Country Saddles added: “Sophie is extremely proactive in taking every available opportunity to promote the [company] name. We are thrilled that she won the award.”
