What we do know is the breeding, and it hints at speed. The father, Harry Angel, was one of the fastest horses in Britain during his racing career, a genuine top-level sprinter who won at the highest level. The mother's side brings in Kodiac, another stallion whose offspring have built a strong reputation as sharp, quick horses who tend to hit the ground running as youngsters.
