Thomas Weston (February 1902 – 1981), born Dewsbury, West Riding of Yorkshire, was a British horse racing jockey.

[1] Through his father, who was a fan of multiple championship winning jockey Steve Donoghue, he developed an interest in the sport of horse racing.

Aged 14 and weighing just 4 st 3 lb (26.8 kg), he became apprentice to Middleham trainer Ned McCormack, a stable controlled by a bookmaker.

[5] He would go on to ride the Horse of the Year in five of the next seven seasons – Colorado (1927), Fairway (1928 and 1929), Gold Cup winner Bosworth (1930) and Hyperion (1933), who would go on to become one of the 20th century's foremost sires.

In 1933 Weston on Hyperion recorded what has been called "the greatest Derby-winning performance of all time"[5] beating high class rivals by an official margin of four lengths, which from photographs has been shown to be closer to eight.

It has been suggested that Weston was in conflict with Colledge Leader, Lambton's successor as Lord Derby's trainer, a situation exacerbated when Hyperion lost that year's Ascot Gold Cup.

"[2] Of his riding, author Quintin Gilbey wrote, "No jockey rode a more vigorous finish and his records showed that though inelegant he was most effective.

[3] He bought his 1927 Eclipse Stakes winner, Cap-a-Pie, after its retirement, for £26 5s at an auction at Folkestone Racecourse, then took it away to be humanely destroyed, allegedly to save it from the dishonour of being used as a cart horse or worse.
