JAGGED Edge was an unusual winner of the Irish Cambridgeshire last Sunday, not because of a 22/1 SP as much as his age, three-year-olds becoming an endangered species in the traditional premier handicaps around a mile, which is a contributing factor to these races being in decline.

As I see it, there are six such races in the calendar: the Lincoln, the mile premier handicaps at the Curragh over Guineas and Derby weekend, the Nasrullah, the Galway Mile and the Cambridgeshire, with three-year-olds allowed to run in all but the Lincoln.
