Allerton Park Horse Trials have been held annually in September for over 20 years, and have become an important date in the British Eventing calendar, attracting about 500 riders from all over the country, and over 2,500 visitors each year.

The Park was originally part of the grounds of Allerton Castle which overlooks our stunning lakeside venue,  that extends over nearly 300 acres of undulating pasture, woodland and lakes.

The four cross country tracks extend throughout the park and include one of the only Advanced tracks in the north of the country, which was added when the Olympic medallist Ian Stark joined our team as designer in 2010.

Allerton Park Horse Trials are fully affiliated to British Eventing, our sport’s national governing body which provides guidance on management, Health & Safety, and technical advice.                                                                                                                                                         

The trials are run as a Limited Liability Partnership with all the net profit being used for improvement of the event facilities and competition tracks, and where possible donations are made to charities eg. Yorkshire Air Ambulance, Riding for the Disabled.




Eventing is an all-round test of horsemanship. It is one of a very few sports that genuinely allow people to compete equally, whatever their experience. Men and women, amateurs and champions, young and experiences horses all compete fairly against each other, making it truly exciting for riders and spectators.

In the one-day format each rider/horse combination competes in Dressage, Show Jumping and Cross Country within a day, so you can see all the phases going on at once.


The Committee is most grateful to the Nell Lady Mowbray for hosting this event and for the many years the Horse Trials has been organised.. We thank our grazier Simon Armstrong who looks after the pasture so well and is exceptionally tolerant of our requests to move his sheep about, and generously loaning his machinery.

Allerton Park Horse Trials Committee are hugely grateful to our enormous band of volunteers who help throughout the year and over the event weekend, without whose help the event would not run.

Another group of generous contributors we wish to thank are our Sponsors, both those that provide financial backing and those whose valued contribution comes in the form of loaned vehicles or services.
