Alderson Factor (Jeffrey Alderson)

Jeffrey Alderson rides with grit, instinct, and relentless drive — a combination that’s become known as “The Alderson Factor.” Known for his aggressive race-riding style and ability to deliver when the pressure is highest, Alderson brings a fearless competitive edge every time he breaks from the gate. Whether it’s grinding down rivals in deep stretch or finding another gear when it matters most, The Alderson Factor is about determination, toughness, and finishing strong.

As a proud Thoroughbred Clothing Co. Partner, Jeffrey represents the culture, passion, and authenticity of the racetrack both on and off the horse. His partnership reflects a shared commitment to the people who live the sport every day — from the backstretch to the winner’s circle.
