Grand National Course and Fences
The Grand National is the ultimate test of horse and jockey. The race comprises two full circuits of a unique 2ľ mile (3,600 metres) course, where challengers will face 30 of the most testing fences in the world of jump racing.
Around 150 tonnes of spruce branches, sourced and transported from forests in the Lake District, are used to dress the Liverpool course's jump fences. Each fence used to be made from a wooden frame and covered with the distinctive green spruce. However, a radical change for the 2013 renewal has seen that frame replaced by a softer, more forgiving material known as "plastic birch", for safety reasons.
Each of the 16 fences on the course are jumped twice, with the exception of The Chair and the Water Jump, which are jumped on the first circuit only. You can take a jockey's eye view of the Grand National course by clicking on the image below:
Following safety reviews after both the 2011 and 2012 renewals, a number of changes have been made to the course.
Changes in 2011 (for 2012)
The landing side of Becherís Brook (fence six on the first circuit and fence twenty-two on the second circuit) was re-profiled to reduce the drop (i.e. the difference in height between the level of the ground on take off and landing) by between 10cm (4 inches) and 12.5cm (5 inches) across the width of the fence. This provided a more level landing area for horses. The drop was reduced to approximately 25cm (10 inches) on the inside of the course and 15cm (6 inches) on the outside of the course.
Levelling work was also undertaken on the landing side of the first fence (fence 17 on the second circuit) to reduce the drop and provide a more level landing. By doing so, this amendment aimed to avoid catching out horses that may Ďover-jumpí the first fence in the early stage of the race. The height of the fence remained unaltered at 4 feet 6 inches (1.37 metres).
The fourth fence was reduced in height by 2 inches to 4 foot 10 inches (1.47 metres). It was identified during the review that fence four and fence six (Becherís) were statistically more difficult to jump than the other fences in all races over the Grand National fences and that was the reason for the change.
Finally, the height of the toe boards on all Grand National fences was increased to 14 inches (36cm). Toe boards are the orange boards, positioned at the base of the fences which provide a clear ground line to assist horses in determining the base of the fence.
Changes in 2012 (for 2013)
Most of the changes for the 2013 renewal focus on the start and the makeup of the fences themselves.
The start of this yearís race will be 90 yards closer to the first fence, reducing the race to four miles and three-and-a-half furlongs, from four-and-a-half miles, while measures will also be taken to stop horses getting caught up in the starting tape.
In particular, the start will now include the 'no-go' zone, which is defined by a line on the track, being extended from 15 yards to around 30 yards from the starting tape.
The starter's rostrum has been moved to a position between the starting tape and the 'no-go' zone to reduce the potential for horses to go through the starting tape prematurely.
The tapes themselves will also be more user-friendly, with increased visibility, while there will be a specific briefing between the starters' team and the jockeys on Grand National day.
The changes to the start may slow the speed the first fence is approached at, while moving the start further away from the crowd will reduce noise that can distract the horses.
The makeup of all of the fences has been changed significantly in 2013. The new fences are still covered in spruce, but wooden posts have been replaced by a softer material known as "plastic birch", and on top of that birch there's a minimum of fourteen to sixteen inches of spruce that the horses can knock off. The outward appearance of the fences remains the same.
Finally, the levelling of landing zones, which started in 2012, has continued this year.
For example, Becher's Brook has undergone further levelling of its wider landing zone, correcting the settlement which occurred following work carried out in 2011.
Fences four, five and 13 have also had their landing areas levelled to smooth out undulations.
Other measures included £100,000 being invested in irrigation to produce the safest jumping ground possible and a new bypass and pen around fence four to catch riderless horses.
There is a hazard to overcome even before the race starts - the build up, parade and re-girthing prior to the off lasts for around 25 minutes, over double the time it takes for any other race.
With 40 starters, riders naturally want a good sight of the first fence and after the long build-up their nerves are stretched to breaking point, which means the stewards' pre-race warning to go steady is often totally ignored.
1 & 17: Thorn fence, 4ft 6in high, 2ft 9in wide - The first often claims many victims as horses tend to travel to it far too keenly. As described above, the drop on the landing side was reduced in 2011.
2 & 18: Almost the same height as the first but much wider at 3ft 6in. The fence became known as The Fan after a mare refused at the obstacle three years in succession, but it lost that name when the fences were relocated.
3 & 19 Westhead: This is the first big test with a 6ft ditch on the approach guarding a 4ft 10in high fence.
4 & 20: Plain fence, 4ft 10in high and 3ft wide. In 2011, the 20th became the first fence in Grand National history to be bypassed on the second circuit, following an equine fatality on the first. In 2012, it was reduced in height by 2 inches to its current height of 4 foot 10 inches (1.47 metres) after it was shown to be the hardest fence on the course to jump along with Becherís Brook. Its landing area has been smoothed out ahead of the 2013 race.
5 & 21: Spruce dressed fence, 5ft high and 3ft 6in wide. Its landing side has also been levelled in 2013.
6 & 22 Becher's Brook: Although the fence looks innocuous from the take-off side, the steep drop on the landing side, together with a left-hand turn on landing, combine to make this the most thrilling and famous fence in the horse racing world. The fence actually measures well over 6 ft on the landing side, a drop of between 5 and 10in from take off. Horses are not expecting the ground the disappear under them on landing, riders need to sit back in the saddle and use their body weight to act as ballast to keep the horses stable.
As described above, there have been a number of alterations to this fence in recent season to try to make it a fairer and safer test for horse and rider.
Becher's Brook earned its name when a top jockey, Captain Martin Becher, took shelter in the brook after being unseated. "Water tastes disgusting without the benefits of whisky" he reflected.
7 & 23 Foinavon Fence: Basically an 'ordinary' fence (4ft 6in high and 3ft wide) that was made famous in 1967 when Fionavon was the only horse to scramble over it at the first time of asking, following a mass pile-up. The jump is the smallest on the course, but coming straight after the biggest drop, it can catch horses and riders out.
8 & 24 Canal Turn: Made of hawthorn stakes covered in Norway spruce, it gets its name from the fact that there is a canal in front of the horses when they land. To avoid it, they must turn a full 90 degrees when they touch down.
The race can be won or lost here, with a diagonal leap to the inside of the jump taking the fence at a scary angle, but reducing the turn on landing. With 30 or more horses often still standing when the field reaches this point on the first circuit, not every rider has the option of taking this daring passage. Before the First World War it was not uncommon for loose horses to continue straight ahead after the jump and end up in the Leeds and Liverpool Canal itself. There was once a ditch before the fence but this was filled in after a mÍlťe in the 1928 race.
9 & 25 Valentine's Brook: The third of four famous fences to be jumped in succession, it is 5ft high and 3ft 3in wide with a brook on the landing side thatís about 5ft 6in wide. The fence was originally known as the Second Brook but was renamed after a horse named Valentine was reputed to have jumped the fence hind legs first in 1840. A grandstand was erected alongside the fence in the early part of the 20th century but fell into decline after the Second World War and was torn down in the 1970s.
10 & 26: Thorn fence, 5ft high and 3ft wide.
11 & 27 Booth: The main problem with this fence, which is 5ft high and 3ft wide, is the 6ft wide ditch on the take-off side.
12 & 28: Same size as the two previous fences, but with a 5ft 6in ditch on the landing side, which can catch runners out.
The runners then cross the Melling Road near to the Anchor Bridge, a popular vantage point since the earliest days of the race. This also marks the point where the runners are said to be re-entering the "racecourse proper". In the early days of the race it was thought there was an obstacle near this point known as the Table Jump, which may have resembled a bank similar to those still seen at Punchestown in Ireland. In the 1840s the Melling Road was also flanked by hedges and the runners had to jump into the road and then back out of it.
13 & 29: Second-last fence on the final circuit, it is 4ft 7in high and 3ft wide. This is the other obstacle to have had its landing side smoothed out ahead of the 2013 renewal.
14 & 30: Almost the same height as the previous fence and it is rare for any horse to fall at the final fence in the Grand National.
15 The Chair: The final two jumps of the first circuit form the only pair negotiated just once - and they could not be more different. The Chair is both the tallest (5ft 2in) and broadest fence on the course, with a 6ft wide ditch on the take-off side.
In addition, the landing side turf is actually raised six inches above the take-off ground. This has the opposite effect on horses and riders to the drop at Becher's, as having stretched to get over the ditch, horses are surprised to find the ground coming up to meet them. This is spectacular when horses get it right and equally so, for all the wrong reasons, when they donít.
This fence is the site of the only human fatality in the National's history, Joe Wynne who sustained injuries in a fall in 1862. This brought about the ditch on the take-off side of the fence in an effort to slow the horses on approach. The fence was the location where a distance judge sat in the earliest days of the race. On the second circuit he would record the finishing order from his position and declare any horse that had not passed him before the previous runner passed the finishing post as "distanced", meaning a non-finisher. The practise was done away with in the 1850s but the monument where the chair stood is still there.
The fence was originally known as the Monument Jump but The Chair came into more regular use in the 1930s.
16 Water Jump: This 2ft 9in fence brings the first circuit to an end and the sight of the runners jumping it at speed presents a terrific spectacle in front of the grandstands. The fence was originally a stone wall in the very early Grand Nationals.
The 474-yard long run in from the final fence to the finish is the longest in the country and has an acute elbow halfway up it that further drains the then almost empty stamina reserves of both horse and jockey.
For numerous riders over the years, this elongated run-in has proved mental and physical agony when the winning post seems to be retreating with every weary stride.
Don't count your money until the post is reached as with the rest of the Grand National course, the run-in can - and usually does - change fortunes.
No visit to Aintree would be complete without taking the opportunity to see some of these famous fences close up. The whole course can actually be walked on the morning of the race (subject to ground conditions and security requirements). Walkers should leave an hour to do a circuit, which must be completed one hour prior to the first race. Maps, guiding racegoers to the start point, are located around the racecourse. The full walk is not available to Steeplechase ticket holders.
