2014: two-year-old season Tiggy Wiggy was ridden in her first three races by Sean Levey. She made her racecourse debut in a five
furlong maiden race on the synthetic
Polytrack surface at
Kempton Park Racecourse on 29 March. Starting the
8/13 favourite, she led from the start and drew away from her eight opponents in the last quarter mile to win by seven
lengths despite being eased down by Levey in the closing stages. Five weeks later she made her first appearance on turf at
Salisbury Racecourse and won by one and a half lengths from Exentricity after leading from the start. The filly was then moved up in class for the Listed Marygate Stakes at
York Racecourse and sustained her first defeat, beaten half a length by the Welsh-trained filly Patience Alexander.
Richard Hughes, took over from Levey as Tiggy Wiggy's jockey after her defeat at York, and rode her in her remaining five races in 2014. At the end of May, the filly was matched against
colts for the first time in the Listed
National Stakes over five furlongs at
Sandown Park. After racing in third place she took the lead inside the final furlong and accelerated clear to win by almost four lengths from the
Brocklesby Stakes winner Cock of the North. At
Royal Ascot in June the filly was again moved up in class for the
Group Three Queen Mary Stakes and started third favourite behind the Irish filly Anthem Alexander and the
Wesley Ward-trained American challenger Spanish Pipedream. She was always among the leaders before challenging inside the final furlong but was beaten a neck by Anthem Alexander. In July at
Newbury Racecourse, Tiggy Wiggy started the 5/2 favourite against twenty-three opponents in the Weatherby's Super Sprint, a race for two-year-olds old at public auction, with the weights being determined by the sale price. Carrying top weight of 127 pounds, she led from the start and quickened away from her rivals approaching the final furlong to win by six lengths from Haxby. In August, Tiggy Wiggy faced Anthem Alexander and the
Albany Stakes winner
Cursory Glance in the Group Two Lowther Stakes over six furlongs at York, after Hannon had considered running the filly against older horses in the
Nunthorpe Stakes. Starting the 15/8 favourite, she led from the start and won by one and a half lengths and three quarters of a length from Cursory Glance and Anthem Alexander in a new track record time, with a gap of five lengths back to the other six runners. After the race Hannon said "She's very, very good. She's always been the sort of filly who draws a gasp and I thought she looked magnificent going out on to the course" but admitted that she was most unlikely to stay further. The form of the Lowther Stakes was subsequently boosted when Cursory Glance won the Group One
Moyglare Stud Stakes at the
Curragh. On 27 September, Tiggy Wiggy moved up to Group One level for the first time for the Cheveley Park Stakes at
Newmarket Racecourse and started the 6/4 favourite against eight opponents. Her main rivals appeared to be Anthem Alexander, the
Prix d'Arenberg winner High Celebrity and the
John Gosden-trained Tendu. As usual, Tiggy Wiggy started quickly and led from the start before accelerating in the last quarter mile. She won by three quarters of a length from Anthem Alexander, with High Celebrity a length and a quarter back in third place. Plans to run the filly against older horses in the
Prix de l'Abbaye in France a week later were abandoned and she was retired for the season.
2015: three-year-old season On her first appearance as a three-year-old, Tiggy Wiggy was tried over seven furlongs in the
Fred Darling Stakes at Newbury in April. She started favourite but finished third behind Redstart and Jellicle Ball. Richard Hannon commented: "Richard Hughes said she wouldn't have won at five, six or seven furlongs today... she probably did get the trip but she has run a little bit lacklustre and below expectations". Tiggy Wiggy faced Redstart and Jellicle Ball again, as well as ten other fillies when she contested the 202nd running of the
1000 Guineas at Newmarket on 3 May. She produced a much better performance, disputing the lead for most of the way before finishing third behind the Irish-trained
Legatissimo and Lucida. Tiggy Wiggy returned to sprinting in June and started at odds of 6/1 for the inaugural
Commonwealth Cup. After being in touch with the leaders in the early stages she weakened in the last quarter mile and was eased down by Hughes to finish sixteenth of the eighteen runners behind
Muhaarar. ==Assessment and awards==
