Standing as the ultimate physical and mental test on the most prestigious racecourse in the world, the highest fence at Aintree commands respect from every jockey and horse that lines up for the Grand National. This formidable obstacle, draped in centuries of racing heritage, represents the very pinnacle of National Hunt racing and serves as the defining feature that separates the contenders from the competitors.
The Monster: The Chair
Officially known as "The Chair," this imposing structure reaches a staggering height of 5 feet and 2 inches, making it the tallest challenge on the entire Aintree circuit. Located at the 19th fence, just before the ultimate test of Becher's Brook, The Chair is notorious for its unique construction. Unlike other fences on the course, it features a formidable "devil's dyke," a steep ditch on the landing side that adds an extra layer of danger and requires precise jumping technique to navigate successfully.
Engineering a Landmark
The physicality of The Chair is matched only by its legendary status in racing folklore. The structure is built with a solid oak frame and covered with spruce, encased in an intricate canvas casing. This specific design provides the necessary resilience to withstand the immense forces generated by top-class contenders, while offering the varying degrees of absorption required to ensure the safety of the athletes, both human and equine, who tackle it.

Historical Significance and Drama
Since its introduction in the early 19th century, The Chair has been the scene of countless dramatic moments, etching its place in Grand National history. It has witnessed both glorious triumphs and heartbreaking falls, serving as a stark reminder of the race’s unforgiving nature. The fence demands absolute commitment; a moment's hesitation or a misjudged stride can lead to disaster, which is why it is often the race's turning point where the lead changes hands.
Strategic Placement
Positioned so late in the race, The Chair acts as a critical filter. By the time the field approaches this monster, horses are fatigued, adrenaline is waning, and the margin for error is razor-thin. Jockeys must balance the need for a strong stride with the conservation of energy, knowing that a mistake here could end their race and their hopes of claiming the coveted Grand National glory.
The Psychological Barrier
Beyond its physical dimensions, the highest fence at Aintree is a psychological giant. The sheer scale of The Chair looms large in the mind of any horse or rider approaching it. The noise of the crowd, the tension in the air, and the visual spectacle of the obstacle combine to create an atmosphere that can unsettle even the most seasoned campaigners.

Respect and Fear
To the racing world, The Chair is a respected adversary. Trainers meticulously prepare their horses for the specific challenges it presents, focusing on building confidence and teaching the precise take-off and landing technique required. For the betting markets and racing pundits, the draw of The Chair is a constant talking point, as it has the power to eliminate favorites and propel longshots into the spotlight with a single, spectacular leap.
Conclusion of an Icon
The highest fence at Aintree is more than just a barrier; it is the embodiment of the Grand National's spirit. It is a test of courage, power, and precision that has defined the sport for generations. The Chair stands as an enduring icon, a final challenge that separates the legends from the merely good, ensuring that every leap over its imposing frame is etched into the history of the race.
