The four-in-hand competition is a carriage driven by four horses, with the reins arranged so that one driver can control all four horses. It is actually now part of an FEI (Fédération Équestre Internationale) World Cup Driving series, which was initiated in 2001. Very little is known of the 1900 event, which had at least 28 carriages entered, although drivers could enter more than once. The title was won by Belgian Georges Nagelmackers, although he had a second entry in the event as well. The four-in-hand event has never again been contested at the Olympics.
The winning quartet of horses were York (a 10-year-old male) and Lady Beatrice (7, mare) leading, with Jack (10, male) and Tom (6, male) following as “wheelers” in the second ranks. Nagelmackers sold both of his teams in October 1900.
