Background
Minoru was a bay horse bred by Colonel William Hall-Walker (later Lord Wavertree) at his stud farm at Tully in County Kildare which today is the Irish National Stud. Minoru was a son of Cyllene, winner of the 1899 Ascot Gold Cup who sired three other Epsom Derby winners, but was exported to Argentina in January 1908, before his true quality as a stallion became evident. His dam was Mother Siegel, a daughter of the highly regarded multiple stakes winner, Friar's Balsam. The colt was leased by his breeder to King Edward VII along with five other yearlings. Minoru was trained by Richard Marsh at his Egerton House stable at Newmarket, Suffolk: Marsh was the established "Royal" trainer, having prepared both Persimmon and Diamond Jubilee to win the Derby for Edward when he was Prince of Wales.Racing career
1908: two-year-old season
Minoru began his racing career impressively, by winning the five furlong Great Surrey Foal Stakes at Epsom, on 5 June, the day that Signorinetta won The Oaks. His subsequent performances in 1908 were disappointing. He finished second to Louviers when strongly fancied for the Coventry Stakes at Royal Ascot in June and was second again to Battleaxe in the July Stakes at Newmarket.After a break, Minoru returned to Newmarket in autumn for two further races. He finished third in the Hopeful Stakes, and third again in the New Nursery, a handicap race for two-year-olds. In the Free Handicap, an end-of-season ranking of the best two-year-olds Bayardo was ranked top with 126 pounds, while Minoru was unrated, meaning that he was at least twenty-two pounds behind the leader. At the end of the year he was considered "useful", but not top class. Marsh, however, thought highly of the colt: when asked to assess the six horses leased by the King from Colonel Hall-Walker, he commented, "I like Minoru best. He is a bit on the leg, but a fine and resolute goer.1909: three-year-old season
Spring
During the winter of 1908–1909, Minoru made exceptional progress, and although the King's racing manager, Marcus Beresford, was initially sceptical, Marsh decided to train the colt for the Classics. The cold weather early in the year delayed the preparation of many horses, including Bayardo, but the lightly-made Minoru took little work to reach peak fitness, giving him an advantage over most of his rivals.After performing impressively in a private trial race, Minoru made his debut in the Greenham Stakes at Newbury on 31 March and won from Valens under top weight of 136 pounds. In the 2000 Guineas at Newmarket on 28 April he started at odds of 4/1 against ten opponents and was regarded as the chief danger to the favourite Bayardo. Ridden by Herbert Joneshe raced prominently before accelerating through a narrowing gap in the closing stages and won easily from Phaleron and Louviers, with Bayardo fourth, in a race record time of 1:37.8. According to press reports the victory was greeted with "intense enthusiasm". Minoru was given very little work by Marsh before his next run in the Derby.Summer

Autumn
On 8 September Minoru attempted to complete the British Triple Crown in the St Leger at Doncaster. Bayardo had meanwhile won four successive races including an easy win over Louviers at Sandown. Minoru started second favourite and finished fourth of the seven runners, six lengths behind Bayardo, who won from Valens and Mirador. Minoru had little luck in running, being unable to obtain a clear run along the rails, but appeared to have been well beaten on merit. Herbert Jones offered no excuses, and admitted that in view of Bayardo's superiority, Minoru had been "a lucky animal" to win the 2000 Guineas and Derby. On his final start of the season, he was sent to Newmarket in October for the Free Handicap, in which he defeated the filly Electra, the winner of the 1000 Guineas and Epsom Oaks, by a neck. As Jones had been injured the previous day, Minoru was ridden on this occasion by Danny Maher, who was presented by the King with a jewelled scarf-pin in recognition of his success. Minoru's performances in 1909 was the key factor in his sire Cyllene being the 1909 Leading sire in Great Britain & Ireland. His prize money of £15,246 placed him second to Bayardo on the list of leading British money-winners.1910: four-year-old season
Minoru was kept in training as a four-year-old with the Ascot Gold Cup as his principal target, but began to develop problems with his eyes. He made his debut in the City and Suburban Handicap at Epsom on 26 April and started 3/1 favourite, but finished seventh of the fourteen runners behind Bachelor's Double. Shortly after Minoru's disappointing run at Epsom the King died and the ownership of the colt was returned to Colonel Hall-Walker. The King's death resulted in the cancellation of all sporting events, including a meeting at Kempton Park Racecourse, where Minoru had been entered in the Jubilee Stakes. The decision was made not to persevere with the horse and he was retired to stud.Assessment
When a new racecourse was opened on Lulu Island, Richmond, British Columbia in 1909 it was named "Minoru Park" in honour of the Derby winner. The track was later renamed Brighouse Park and closed in 1941, although the name lives on in playing fields and an ice rink on the site under the name of "Minoru Park". In their book A Century of Champions, Tony Morris and John Randall rated Minoru an average winner of the 2000 Guineas and an inferior winner of the Derby.Stud record
Minoru stood as a stallion at Hall-Walker's Tully Stud in County Kildare, Ireland at an initial fee of 98 guineas., Minoru produced the excellent broodmare Serenissima before being sold in 1913 to a breeding operation in Russia. Serenissima's foals included:- Selene (b. 1919) - outstanding broodmare, dam of Britain's Hyperion, and stallions Sickle and Pharamond II who were successful sires in the United States
- Tranquil (b. 1920) - won the 1,000 Guineas Stakes and St. Leger Stakes
- Bosworth (b. 1926) - winner of the Ascot Gold Cup
