Marquand's fledgling career has gone from Champion Apprentice with Richard Hannon, to a first Group One in Australia on Addeybb, via a high profile romance with fellow jockey Hollie Doyle.
Richard Hannon connection
The 2015 season saw Marquand take the Champion Flat apprentice jockey title in only his second term in the saddle.
Marquand totted up 67 wins, including a nice victory in a Class 3 handicap at Sandown on Who Dares Wins for his boss Hannon. The year was completed by Marquand's inclusion in the final three shortlist for the BBC Young Sports Personality of the Year.
The 2016 season saw a slight reduction in winners from 67 to 63 as Marquand found his feet, but a sharp increase in prize money collected to £604,244.
Marquand won on horses for various trainers in 2017, including Brian Meehan and Robert Cowell but his standout victory came in a first Group success at Salisbury in September.
Marquand produced a 40/1 shock aboard Anna Nerium in the Group Three Bathwick Tyres Dick Poole Fillies' Stakes.
In 2018, Marquand celebrated his first hundred winner season, while old favourite Who Dares Wins provided a long-range victory in the two mile Northumberland Plate in June 2019.
Then came a call from down under.
First Australian adventure
After collecting a tonne of winners, Marquand made the bold move to Australia in search of more experience and success.
Standouts include a victory aboard Prime Star in the Inglis Millennium at Warwick Farm and then a first Group One victory for Marquand in the Ranvet Stakes at Rosehill aboard the promising Addeybb for William Haggas.
"What a super ride by Tom Marquand."— Racing NSW (@racing_nsw) March 14, 2021
Just six days until we see round 3 of Addeybb vs Verry Elleegant in Saturday's Group 1 Ranvet Stakes (2000m) at @rosehillgardens. Who could forget this two horse war from 2020?! @tabcomau @tommarquand @mcacajamez @7horseracing @hkdarren pic.twitter.com/Kawm4xwFPR
Marquand topped off his first stint down under with a superb win in the Group One Queen Elizabeth Stakes on Addeybb, earning a sizzling prize of £674,338.62 at Randwick in April 2020.
Earning the nickname "Aussie Tom", Marquand secured 26 winners at a strike rate of 17 per cent in his first Aussie stint.
Back home to a St Leger win
A trio of Group Three wins came next at Newcastle, Goodwood and Deauville but the crowning glory would come in the 2020 St Leger.
Marquand's inclusion in the race was a stroke of luck for him but unfortunate for Shane Crosse who was booked to ride Galileo Chrome but tested positive for Covid-19 in the build up.
Marquand chose Hannon over Andrew Balding early in his career and it was a Balding horse in Berkshire Rocco that the jockey beat home in a thrilling finish on Town Moor.
Galileo Chrome was a game victor by a neck, earning the then 22-year-old Marquand a first English Classic while the jocked-off Crosse watched on ruefully at home.
Back Down Under
All eyes were on the Waller trained favourite Verry Elleegant at Randwick but the astute punters backed Marquand on Addeybb and the Haggas globetrotter held on for a game half-length victory to take the hefty £1,367,696 prize.
Marquand had shown boomerang abilities to come back and win the prestigious Aussie race, once again showcasing his versatility.
Back in Britain and in the winners
If Marquand was suffering from jet lag after his journey back from Australia he wasn't showing it as he won the Sandown Derby trial just six days after victory at Randwick.
Although Marquand could only finish 8th in the Derby on Youth Spirit he did take a decent Epsom win in the Group Three Diomed Stakes aboard regular mount Oh This Is Us.
Tom Marquand's net worth is reported to be £10million.
