What we do know is where Sir Topham Hatt comes from. The father is Walk In The Park, a sire with a strong record of producing horses built for jumping, and the mother's side carries the influence of Oscar, another stallion associated with stamina and jumping ability. In short, the breeding suggests this is a horse designed for the jumps rather than the flat, and at six years old, the debut comes at a more mature age than many — which in jump racing is not unusual, and sometimes means a horse has been given plenty of time to develop at home before being asked to perform in public.
Beyond that, the first race will tell us everything. Watch how Sir Topham Hatt settles, how it jumps, and how it finishes. That is when the story really starts.
