Winx:
Winx (foaled 14 September 2011) is a retired champion Australian Thoroughbred racehorse and now an active broodmare She is widely regarded as one of the greatest racehorses in history, particularly noted for her unprecedented winning streak and dominance in elite races Over her career, Winx won 37 of her 43 starts, including her final 33 races consecutively—a streak that began in May 2015 and ended with her retirement in April 2019 This sequence included a record 25 Group 1 victories, the most by any horse globally
Trained by Chris Waller and ridden primarily by jockey Hugh Bowman, Winx raced in the silks of Magic Bloodstock Racing, R G Treweeke, and D N Kepitis She was bred in Australia by Fairway Thoroughbreds and sired by Street Cry, whose other notable progeny include Zenyatta and Street Sense Her dam, Vegas Showgirl, was a stakes winner in New Zealand The name "Winx" was inspired by a Las Vegas burlesque memory of co-owner Richard Treweeke, linking it to the phrase "wink" at dancers, combined with the phonetic similarity to her dam's name
Winx's racing success spanned distances from 1,300 to 2,200 metres, showcasing her versatility and stamina She became the first horse to win the prestigious Cox Plate four times (2015–2018), a feat that solidified her legendary status In the World’s Best Racehorse Rankings, she was the top-ranked filly or mare in 2016, 2017, and 2018, and in 2018, she was co-ranked as the best horse in the world alongside Cracksman She earned over A$26.4 million in prize money, making her one of the highest-earning racehorses in history
Despite not having a particularly long stride—measured at 6.76 metres compared to nearly 8.5 metres for horses like Black Caviar—her success was attributed to an exceptional cadence, taking 14 strides every 5 seconds, allowing her to accelerate at will during races She was inducted into the Australian Racing Hall of Fame in 2017, only the third horse to receive the honor while still active Her final race was a victory in the Queen Elizabeth Stakes at Randwick on 13 April 2019, after which she was retired to stud
