His attempt to become the first Triple Crown winner since Rock Sand in 1903 however, ended in failure.

Rock Sand (1900-1914) was a British Thoroughbred race horse and sire.

Rock Sand was trained throughout his career by George Blackwell at Newmarket, Suffolk.

As the horses went into the winter break, Rock Sand was 4/1 favourite for the following year's Derby, with Flotsam the second choice.

The Sportsman magazine noted that Rock Sand was a rather lazy colt who "does not gallop until he is compelled to".

Ard Patrick had been retired by this time but Rock Sand was opposed by Sceptre.

Zinfandel won easily from Sceptre, with Rock Sand third.

Rock Sand avoided Zinfandel for the remainder of the season and was unbeaten in his remaining five races.

Rock Sand retired to stud in England, but when James Miller died in 1906 he was put up for sale.

Rock Sand was inbred 4x4x4 to Stockwell, meaning that this stallion appears three times in the fourth generation of his pedigree.
