ARCTIC Cosmos produced a career-best performance in 2010 when he won the Group 1 St Leger at Doncaster, and it was no ordinary renewal of the classic. Three lengths and more in arrears were such international Group 1 stars as Snow Fairy, Joshua Tree and Rewilding.

Trained by John Gosden, Arctic Cosmos was from the first crop of the Derby winner North Light (Danehill) and he retired to James Hannon’s The Old Road Stud where he has remained. Now he has sired a standout winner from his own first crop, this being the seven-year-old mare Waitnsee.
