Izzi Top made her debut in a maiden race for two-year-old fillies at
Doncaster Racecourse. She started a
33/1 outsider and finished second. In April 2011 Izzi Top won a maiden race at
Windsor Racecourse but was later disqualified when a prohibited substance was detected in a post-race sample. In May she finished third in a ten
furlong race at Newmarket and then won a Listed race over the same distance at
Newbury Racecourse. In June she started a 25/1 outsider for
The Oaks but exceeded expectations by finishing third to
Dancing Rain. Izzi Top's only other appearance of the season came more than four months later in the Group Three Prix de Flore at
Saint-Cloud Racecourse. She started the 3.1/1 favourite and won by a head from Albaraah. In May 2012, Izzi Top won the Dahlia Stakes at Newmarket and the Middleton Stakes at
York in May. In July she was sent to Ireland to contest the Group One Pretty Polly Stakes at the
Curragh. She won her fourth consecutive Group Race comfortably by one and a quarter lengths from the odds-on favourite
Sapphire. On 4 August at
Goodwood Racecourse, Izzi Top started favourite for the Group One
Nassau Stakes but was badly hampered in the final furlong and finished sixth of the eight runners behind her three-year-old stable companion
The Fugue. Two weeks after her run at Goodwood, Izzi Top finished second to
Snow Fairy in the Prix Jean Romanet at
Deauville Racecourse, but was later awarded first place when the winner failed a post-race test. On her final appearance, Izzi Top finished second to Ridasiyna when favourite for the Prix de l'Opéra. ==Breeding career==
