In all he won twenty-one times in thirty-six races for four different owners before being retired to stud, one of which was Mr Hallett Esq, where he proved to be a successful sire of winners.

He was one of many good horses, including Barefoot, bred and owned by the partnership of the Reverend Henry Goodricke (Rector of Aldborough) and Giles Crompton.

His dam, Miss West, was a "celebrated" broodmare who produced many good winners for Goodricke before dying at Aldborough at the age of twenty-five in early 1802.

Two days later Quiz was runner-up to Lord Darlington's colt Muly Moloch in a two-mile sweepstakes, showing improved form to beat Lenox into third.

[4] On 22 September, Quiz was one of eight colts, from an original entry of eleven, to contest the twenty-sixth running of the St Leger Stakes over two miles at Doncaster Racecourse.

He began his four-year-old campaign at Newmarket's Craven meeting in April where he won a 100 guinea match race against Mr Payne's unnamed colt, carrying thirty-two pounds more than his rival.

At the Second Spring meeting two weeks later, Quiz contested the Jockey Club Plate in which he defeated the 1799 St Leger winner Cockfighter over the four mile Beacon Course, despite being opposed in the betting.

[11] On the opening day of the First Spring meeting two weeks later Quiz walked over for a subscription race over the Round Course to claim his seventh "win" in succession.

[12] At the Second Spring meeting in May, Squire Teazle and Babylon were both withdrawn from match races against Quiz over the Beacon Course, enabling Dawson to collect 150 guineas in forfeits without having to run his horse.

[7] On 20 May Quiz won his second Brocket Hall Gold Cup, walking over the three and a half mile course when the other fourteen runners were withdrawn by their owners.

[13] On 16 April at Newmarket, Quiz began his fourth season by beating Mr Delmé Radcliffe's horse Driver in a subscription race over the Round Course.

In the following month he appeared at Reading in Berkshire where he carried top weight of 126 pounds to a half length[19] victory in the local Gold Cup.

[25] Quiz's final season as a racehorse began, as usual, at the Craven meeting, where he finished fifth of the seven runners under a weight of 129 pounds in a division of the Oatlands Stakes.

Quiz was matched against Lord Sackville's five-year-old Bustard and recorded his last victory by winning "very easy"[26] at odds of 5/2 over the Beacon Course.
