The Grand National Fences

 

The Grand National fences are arguably the most famous horse racing steeplechases in the world. Dating back to 1829, racing over fences at Aintree Racecourse has evolved over the years, proving to be one of the most challenging tests, over distance, for runners and riders.

 

 How many fences are in the Grand National?

 

In total there are 16 fences on the Grand National course, 14 of which are jumped twice along the four mile, two and half furlong distance, which is the longest Jump racing distance in the UK.


The fences used to be constructed from natural thorn hedges and were known as ‘thorn fences’. However, they are now created from Sitka or Norway spruce, which is brought down from the Lake District, and it is weaved into plastic birch structure which provides flexibility should a runner make a mistake at the jump. It takes the Aintree Groundstaff team three weeks to build the fences from 16 lorry-loads of spruce prior to the Grand National Festival.

 

There are many well-known fences at Aintree including Becher’s Brook, Canal Turn and Valentine’s, all of which provide different tests for the runners and rider. Each fence varies in height, with the lowest measuring at 4ft 6” and the highest, The Chair, at 5ft 2” which also has a 5ft wide ditch on the take-off side.

 

The Grand National Fences

1 & 17 4ft 6in high, 2ft 9in wide.


The first fence marks the start of the Grand National race and is in fact one of the smallest on the course. It is parallel to the Embankment, the large slope to the right of the course which houses 13,000 racegoers, all eager to see the horses begin their trip over the fences. This is a ‘settling’ fence and helps the runners and riders find their stride at the beginning of the race.

 

2 & 18 4ft 7in high, 3ft 6in wide.

 

3 & 19 – Open Ditch

 

5ft high, 10ft 6” (total length with ditch and fence)

 

This is the first of three open ditch fences on the course, this being on the take-off side and measuring 7ft wide.

 

At 5ft high, it is also known as ‘Westhead’ after the late Steve Westhead who was one of Aintree’s fence builders and worked at Aintree Racecourse in the 1970s.

 

4 & 20 4ft 10in high, 3ft wide.

 

5 & 21 5ft high, 3ft 6in wide.


The landing side was levelled in 2013.

 

6 & 22 - Becher’s Brook 4ft 10” high, 7ft 6” wide

 

The most famous fence in the Grand National race is named after Captain Martin Becher who landed in the ditch after being unseated by Conrad in the first official Grand National race in 1839.

This fence has been remodelled several times, with the drop on the landing side levelled in the 1990s and again after the 2011 Grand National race.

 

7 & 23 – Foinavon Fence 4ft 6in high, 3ft wide.

 

This otherwise ordinary fence became extraordinary in 1967, when Fionavon was the only horse to successfully jump the fence after multiple horses shied and caused chaos on the course, going from last place to win the race.

 

8 & 24 – Canal Turn 5ft high, 7ft wide


This fence gets its name from the nearby Leeds-Liverpool canal and is noted for the sharp, 90-degree, left-hand turn that the runners have to take as soon as they have jumped the fence.

 

9 & 25 – Valentine’s Brook 5ft high, 7ft wide

 

With a 5ft 6in brook on the landing side, this fence was originally known as Second Brook, but was renamed after a horse called Valentine was said to have jumped it hind legs first in 1840.

 

10 & 26  5ft high, 3ft wide.

 

11 & 27 – Open Ditch fence 5ft high, 10ft spread

 

This is the fence where red-hot favourite, Golden Miller fell after refusing to jump in the 1935 Grand National race. He won in record time in the previous year, 1934, and became the first horse to win the Cheltenham Gold Cup and Grand National race in the same season.

 

12 & 28  5ft high, with a 5ft 6in ditch on the landing side

 

Also known as ‘Booth’ after the late John Booth, which was the foreman of Aintree’s maintenance team in the 1970s.

 

13 & 29 4ft 7in high, 3ft wide.

 

This fence had its landing side smoothed out prior to 2013.

 

14 & 30  4ft 6in high.

 

Although few horses fail here, it may lead them into a false sense of security before facing The Chair.

 

15 – The Chair

 

The highest fence in the race at 5ft 2”, The Chair has a 5ft ditch before the fence and a raised landing side. Jumped only on the first circuit, it’s named after the chair the distance judge used to sit in to gauge the official distance between the winner and the runners behind. These horses were classed as ‘beaten by a distance’, with a ‘distance’ being more than forty lengths.

The original ‘chair’ is now located on a podium in the Red Rum Garden at Aintree Racecourse. 

 

16 – Water Jump  2ft 6in high.

 

The final fence on the first circuit is the lowest of the 16 fences. It has a wide stretch of water on the landing side and was first introduced in 1841, replacing a stone wall which was, at the time, 16ft wide!
