Mayson, a bay horse with a white snip[1] was foaled on 16 May 2008 and is a son of Haydock Sprint Cup winner Invincible Spirit.

Mayson was bred at David Armstrong's Highfield Farm stud[2] near Coppull in Lancashire[3] and is the first foal of his dam, Mayleaf, a daughter of Nunthorpe Stakes winner Pivotal.

Ridden by Paul Hanagan for the third time, he finished in fourth place, about two and a half lengths behind winner Zebedee.

Ridden by Neil Callan for the first time, he started at 28/1 and finished in sixth of the seven runners, over five lengths behind winner Temple Meads.

As they entered the final furlong he took the lead and ran on to win by three and a half lengths from the gelding Jimmy Styles,[8] gaining his first victory for twenty months.

As he had done in the Abernant Stakes, he took the lead entering the final furlong and went on to win by three quarters of length from Definightly, who just beat Elusivity for second place.

[14] Mayson was being trained for the British Champions Sprint Stakes on 20 October, but after suffering a bruised foot in the Prix de l'Abbaye he failed to recover in time and was retired to stud.

[17] c = colt, f = filly In November 2012, Mayson was very narrowly beaten by the Australian mare Black Caviar for the title of European Champion Sprinter at the Cartier Racing Awards.
