Leading Light  Leading Light (foaled 6 March 2010) is an Irish Thoroughbred racehorse. As a two-year-old, he was well-beaten in his first race before winning a maiden race. In 2013, he established himself as a leading stayer, winning his first four races, including the Gallinule Stakes, the Queen's Vase, and the classic St Leger Stakes. As a four-year-old, he won the Vintage Crop Stakes before winning the Ascot Gold Cup. Leading Light is a bay horse with a broad white blaze and a white coronet on his right foreleg bred in Ireland by Lynch-Bages Ltd. He is one of many top-class horses sired by Montjeu. Others include the Derby winners Motivator, Authorized, Pour Moi and Camelot, the St Leger winners Scorpion and Masked Marvel, and the Prix de l'Arc de Triomphe winner Hurricane Run. Leading Light's dam Dance parade was a top-class racemare whose wins included the Queen Mary Stakes and the Fred Darling Stakes. In October 2011, the yearling was consigned by the Glenvale Stud to the Tattersalls sales at Newmarket. He was bought for 520,000 guineas by the bloodstock agent Dermot "Demi" O'Byrne, acting on behalf of John Magnier's Coolmore organisation. He was sent into training with Aidan O'Brien at Ballydoyle. Like many Coolmore horses, the details of Leading Light's ownership change from race to race. He has sometimes been registered as being owned by Derrick Smith, while on other occasions he races for the partnership of Smith, Susan Magnier and Michael Tabor. Leading Light made his racecourse debut in a one mile maiden race at Galway Racecourse on 4 August 2012. Ridden by Seamie Heffernan, he started at odds of 100/30 and finished fourth of the five runners, fifteen lengths behind the winner, Sugar Boy. After a break of two months, Leading Light reappeared in a nine-furlong maiden race on heavy ground at Tipperary Racecourse where he was ridden by Kevin Manning. Starting favourite against eight opponents, he took the lead inside the final furlong and won by one and a half lengths from Silky Pyrus. Leading Light made his first appearance as a three-year-old in a minor race over ten furlongs at Navan Racecourse on 7 May.
