The British Open Show Jumping Championships were launched in 2003 and have been held indoors during April of every year since.
The Championships have a unique competition format with the champion being determined by ongoing placings in three qualifying rounds and the final.
One of the reasons for this is its policy of only inviting the top British and international show jumpers to compete.
In its international classes, only the best (as defined by the British Showjumping Association) can participate.
The British Open also hosts national show jumping classes and is the Final for the BSJA Winter Grand Prix and the BEF Under 23 Classic and Championship.
