Solario

Bred in Ireland by the 4th Earl of Dunraven, he was by the 1918 English Triple Crown champion, Gainsborough. His dam Sun Worship, was a daughter of the outstanding sire Sundridge who was the Leading sire in Great Britain & Ireland in 1911.^[1]

Solario was sold as a yearling for the huge sum of 47,000 guineas to a British syndicate.^[2] Sir John Rutherford employed Reginald Day to condition the colt for racing.

At age two, Solario won the 1924 Exeter Stakes and was second to Picaroon in the Middle Park Stakes. As a three-year-old, he finished fourth in the first two British Classic Races then won the third, the St Leger Stakes. At Ascot Racecourse he won the 1925 Ascot Derby. At age four, Solario ran away from the field while winning the 1926 Coronation Cup by fifteen lengths then won the Ascot Gold Cup.

Solario commenced stud duties at Newmarket at a fee of 500 guineas a mare.^[2] In 1932 he was sold following the death of his owner, Sir John Rutherford. In his will, Rutherford left two pictures of Solario and the Coronation Cup he won to the Blackburn Museum and Art Gallery. Solario was sent to stand at Terrace House Stud (now Tattersalls' Park Paddocks in Newmarket, Suffolk). In 1937, he was the Leading sire in Great Britain & Ireland when his son Mid-day Sun won The Derby and his daughter Exhibitionnist won the 1,000 Guineas Stakes and Epsom Oaks. Solario sired his second Epsom Derby winner when another son, Straight Deal, won the 1943 running.

Solario died at the age of 23 in 1945, having sired the winners of £270,000 in stakes.^[2] He is buried at Tattersalls' Park Paddocks in Newmarket.
