The Cox Plate has a centenary of history having first been run in 1922 and its timing means the winner gains ballot exemption for the Melbourne which runs 10 days later..
Every race has been run at Moonee Valley over varying distances but all races have been for stayers. The 1922 race started with 9 ½ furlongs (1911m), the length was increased to 10 furlongs (2011m) in 1943, then in 1972 with the metric system it was shortened to 2000m, increased to 2050m in 1974, before finally settling on 2040m in 1986.
A golden period for the race was during the period 1999 to 2005 when the Cox Plate was including in the (now defunct) Emirates World Series Racing Championship, a sort of grand prix of horse racing which included 10 famous races:
- UK – Ascot - King George VI and Queen Elizabeth Stakes
- Japan – Tokyo - Japan Cup
- UAE – Dubai - Dubai World Cup
- USA – Arlington Heights - Arlington Million
- Hong Kong -Hong Kong Cup
- Canada – Toronto - Canadian International Stakes
- Germany – Baden Baden - Grosser Preis von Baden
- Ireland – Leopardstown - the Irish Champion Stakes
- USA – different racetracks - Breeders' Cup Turf and Breeders' Cup Classic
Favourites have a win percentage of approx. 41% with 43 winners, more recently 6 favourites have won in the last 10 years (others being 1 x 2nd, 2 x 3rd and 1 x 8th) and 10 in this millenium.
A Melbourne Cup and Cox Plate double in the same year has been achieved 7 times including Phar Lap and Makybe Diva
1980 to 1982 was the time of Kingston Town who won 3 consecutive Cox Plate races. But the most famous winner of all must be Winx who, from 2015 to 2018,won 4 consecutive races and set the course record for the race twice!
Many horses have won the race twice, some consecutively, including Phar Lap (1930,1931), Northerly (2001,2002), Beau Vite (1940,4941), Flight (1945,1946), So You Think (2009,2010), Sunline (1999,2000), Tobin Bronze(1966,1967) and Young Idea (1946,1947). Unfortunately,Anamoe has retired so it will not happen again in 2023, James McDonald will be looking for a new ride and James Cummings (whose grandfather Bart Cummings trained consecutive winner So You Think will looking to train another winner.
Successful jockeys have included 5 times winner Darby Munrobetween 1933 and 1952, 4 times winners Hugh Bowman (on Winx) and Jack Purtell between 1950 and 1956.
If you are looking at successful trainers, T J Smith trained 7 winners between 1957 and 1984 plus Jack Holt had 6 winners between 1923 and 1947. Most recently, well of course, Winx will have done Chris Waller proud with 4 winners.
