Tullius started his career in some very ordinary races but has kept on improving, mixing it with some of the best milers in Europe despite suffering serious injury in 2012.
Purchased from his Italian breeders for just £21,000, in 2009, he was initially trained in Surrey by Peter Winkworth and did well for him, winning three of his first ten outings and finishing second on four other occasions.
But it was not until he joined his present handler, Andrew Balding, upon Winkworth’s retirement in late 2011, that he really began to blossom.
He won his first three races for Balding – a Newmarket handicap and Listed contests at Windsor and York – before a third place in a Group 2 event at Ascot was followed by a breakthrough first Pattern success in the Sovereign Stakes at Salisbury in August 2012.
However, he then suffered a leg fracture that kept him on the sidelines for 14 months.
He took a little time to get back to his peak upon his return to the racecourse and could do no better than a solitary third place in his three races during the autumn of 2013.
Fully fit again for the start of the 2014 campaign, he proved a different horse. He begun with an excellent second under a big weight in one of the biggest handicaps of the season, the William Hill Lincoln, and then underlined his liking for soft ground when storming home almost four lengths clear in the Group 2 bet365 Mile at Sandown.
He is also effective on faster surfaces, as he showed when chasing home Olympic Glory on his QIPCO British Champions Series debut in the Al Shaqab Lockinge Stakes, before fourth place in the Queen Anne Stakes. After a break he could only manage fourth in the Group 2 Shadwell Joel Stakes.
Never one to be in the doldrums for long, Tullius then ran a superb race in the Queen Elizabeth II Stakes on QIPCO British Champions Day, when a close fourth to the outstanding Solow.
And he showed himself to be as good as ever in 2016 when, visored for the first time, he won the Diomed Stakes at Epsom.
