'As an afterthought, I decided I should do a £1 each-way acca - I won £550,000'

Twenty-five years ago, Frankie Dettori's life was changed forever in a single afternoon. So too was racing history. A quarter of a century later his Magnificent Seven is no less magnificent.

Dettori went to Ascot on Saturday, September 28, 1996, as the reigning champion jockey. He was there for the Festival of British Racing, a seven-race card highlighted by the Queen Elizabeth II Stakes, in which Godolphin's retained rider was booked to partner 2,000 Guineas winner Mark Of Esteem.

Dettori won that race and all the other races. It was an epoch-making achievement. Prior to Dettori, only two jockeys – Sir Gordon Richards and Alec Russell – had gone through an entire British card undefeated, but they did that at fixtures with only six contests. The nearest comparison to what took place at Ascot occurred at Stockbridge on June 18, 1867, when George Fordham won six of the seven races and dead-heated on an odds-on favourite in the other, only to then lose in a run-off.
