Based on his past history, probably no more than four or five runs. The nearest equivalent to CH was Caracciola, bought off the flat from Germany, he started out over hurdles for Henderson as a 5-y-old.
For the next four years he was kept to just NH races, becoming a regular in the run of high value 2M handicap hurdles at Newbury, Cheltenham, Ayr and Haydock in the period from Feb – May. Then when he was a 10-y-old, after running in most of those races, he was sent flat racing. That year he finished second in the Ascot Stakes and second in the Cesarewitch.
The key difference was that he’d never fallen and he continued to mix flat and hurdling. On the flat he won the Cesarewitch as an 11-y-old and the Queen Alexandra as a 12-y-old. The last race of his career was the Goodwood Cup as a 13-y-old! So we might see CH for a few years yet.
Henderson also won the Cesarewitch with two other older horses, Landing Light and Buzz, both primarily hurdlers. And all three of those Ces winners ran almost always at 2M over hurdles, but handled the longer trip on the flat.
