Workforce has been retired to stand at Shadai Farm in Japan. The 2010 English Derby and Arc de Triomphe winner bowed out of racing after an unplaced run in this year’s Arc.
A Juddmonte Farms homebred, Workforce is a son of King’s Best who also sired last year’s Japan Derby winner Eishen Flash.
His former stablemate Harbinger covered his first book at Shadai earlier this year. Harbinger (Dansili) was a G1 winner of the 2010 King George at Ascot for Highclere Racing and trainer Sir Michael Stoute.
During an outstanding three-year-old campaign, Workforce was trained by Stoute to win the English Derby by seven lengths in record time and then the Arc, in which he beat the Japanese challenger Nakayama Festa.
He returned this term to win the G2 Brigadier Gerard Stakes at Sandown in May and followed up seconds to So You Think in the G1 Eclipse Stakes and Nathaniel in the G1 King George.
Workforce (4c King’s Best – Soviet Moon by Sadler’s Wells) is from an unraced sister to English St Leger winner Brian Boru.
Darley shuttled King’s Best to Australia for three seasons until 2004. A Group 1 winning son of Kingmambo, he has a winning strike-rate of 55% in Australia & NZ but didn’t sire a single stakes winner down here.
