Big Ben (April 20, 1976 – December 11, 1999) was a world champion show jumping horse and famous Belgian Warmblood.

Millar and Big Ben also won the du Maurier International twice, in 1987 and 1991, the world's richest grand prix event at that time.

In 1992 Big Ben survived two bouts with colic and an accident in which his horse trailer overturned on a highway after a head-on collision with a car.

The book documented the challenges, such as the two bouts of life-threatening colic surgery, that Big Ben faced inside and outside the competitive ring.

It features original research and interviews with Ian Miller and Big Ben's personal groom, Sandi Patterson.

His dam, Oekie, was a 15 hands (60 inches, 152 cm) chestnut mare who was 3⁄4 Gelderlander and 1⁄4 Selle Français, registered as a Belgian Warmblood.

Big Ben was descended in the male line from Precipitation (1933 – 1957), an influential British-bred Thoroughbred stallion who is found in the pedigrees of many racehorses and sport horses today.
