London International Horse Show

The show is held over six days during the week preceding Christmas, and typically involves over 400 horses and ponies.

Reginald Gardiner Heaton, a horse breeder from Chatteris in Cambridgeshire, is said to have thought up the show.

Early in 1906, Gardiner Heaton invited friends to dinner with the intention of persuading them to organise an international show on similar lines to those in New York, Paris and Brussels.

The directors listed in early programmes included many prominent and wealthy patrons, with at least 10 dukes, 11 marquises, 54 earls, 25 viscounts, 80 barons, and 28 knights who were made honorary vice-presidents.

[3] The Olympia London International Horse Show celebrated its 100th anniversary in 2007 as "one of Europe's oldest equine competitions".

It also houses additional Kennel Club Dog Agility Classes and various Masterclasses with key individuals from the equestrian world.

Participants have included the Metropolitan Police Service's mounted regiment, the Household Cavalry and the King's Troop, Royal Horse Artillery.
