uick was born in Norway in 1988, where his Scottish-born father, Walter, was Scandinavian champion jockey on eight occasions and his mother, Maria, a dressage rider and showjumper. He has two younger brothers called Martin and Andrew. 

Buick was riding horses from a young age and used to ride out in the mornings before going to school. Fluent in Norwegian, Danish, English and German, Buick was a regular visitor to the UK, where he spent summer holidays riding out for trainers Reg Hollinshead, Marcus Tregoning and Andrew Balding. After completing his education abroad, he joined Balding as an apprentice jockey. 

From that moment onwards, through an innate mixture of drive, determination and talent, William Buick has undoubtedly become one of the finest and most decorated riders in the world of flat racing.

He has won over 110 Group One races worldwide and has registered 33 wins on one of the biggest stages of all, Royal Ascot. In addition, Buick has claimed 5 British Classics including the Derby, 1000 Guineas and 2000 Guineas (the latter as recently as 2024). 

His close relationships with John Gosden and Charlie Appleby have without doubt provided Buick with a platform to show his talent in the biggest races and whilst he remains as the retained jockey to Godolphin, the 37 year-old will continue to show no signs of slowing down.
