Lounger was a bay horse bred by his owner Gilbert Crompton, who operated his racing interests in partnership with the Reverend Henry Goodricke, Rector of Aldborough.
[4] Lounger's racing career began at Beverley Racecourse, where he finished third to Mr Bethell's unnamed grey filly in a sweepstake over one and a half miles on 14 June.
[6] On 26 September, Lounger was one of eight colts, from an original entry of twelve, to contest the twenty-second running of the St Leger Stakes over two-miles at Doncaster Racecourse.
Ridden by John Shepherd, Lounger created an upset by winning the classic from the favourite, with the first two being the only finishers officially placed by the judge.
[10] He took his winning run to six at York in August when he defeated Thomas Gascoigne's Timothy in a 250 guinea match race, but was beaten into second place by Stamford in the four mile Ladies' Plate later in the meeting.
At the next Newmarket meeting later that month he finished third to Diamond and Stamford in the Jockey Club Plate, and third again in a handicap race over the two mile "Ditch-in" course.
Lounger made his final appearance at Bedford Racecourse on 10 September when he was beaten by Charles Bunbury's colt Combatant, his only opponent in the Woburn Stakes, a four-mile claiming race.
