As a two-year-old she was beaten in her first two races, but her five-lengths win in the Cherry Hinton Stakes at Newmarket Racecourse was enough to see her rated among the best juveniles of the year.
[5] An unusual feature of Sweet Solera's pedigree was the presence in the fourth generation of Call Boy: the 1927 Epsom Derby winner was almost sterile and sired very few foals.
Sweet Solera's pedigree was not considered an impressive one[6] and when she was sent as a yearling to the October sales at Newmarket she was bought for 1,850 guineas by the trainer Reg Day, acting on behalf of Mrs S. M.
[7] Day, who began training racehorses as a teenager in 1900, prepared the filly for racing at his Terrace House stables at Newmarket, Suffolk.
Sweet Solera was being prepared for a run in the Cheveley Park Stakes in October when she contracted a respiratory infection which brought an end to her season.
[9] The top weight of 133 pounds was given to the French-trained filly Opaline, who had won the Cheveley Park Stakes in Sweet Solera's absence.
She won by three-quarters of a length from the colt Henry The Seventh,[2] but appeared fortunate not to be disqualified, having hampered the runner-up in the closing stages.
In the 1000 Guineas over the Rowley Mile at Newmarket, Sweet Solera was ridden by Bill Rickaby and started the 4/1 joint favourite with Mystify in a field of fourteen fillies.
