Changes to Grand National course announced Aintree Racecourse and the British Horseracing Authority (BHA) have announced the interim findings of their review into the 2011 John Smith's Grand National meeting. The findings of the Grand National Review Group relate specifically to the Grand National Course and its fences, which will be subject to a balanced package of modifications with the aim of enhancing safety for competitors. The balanced changes to the course and fences follow detailed expert analysis of all races run on the Grand National Course since 1990 (when the course was significantly remodelled). In addition, consultation has been conducted with the RSPCA and World Horse Welfare and invaluable input has been provided by leading trainers and jockeys in conjunction with the National Trainers Federation (NTF) and Professional Jockeys Association (PJA). Work will now commence to ensure all modifications are fully bedded-in ahead of Aintree's next race on the Grand National Course, the Becher Chase on Saturday, December 3, 2011. Julian Thick, Managing Director of Aintree Racecourse, said: "The safety and welfare of horses and riders is always our number one priority at Aintree. This is the latest stage in our continuous drive to make the Grand National Course as safe as possible. The Grand National is an unparalleled challenge over four miles and four furlongs and this unique event is the most famous race in the world. "It is not possible to completely eliminate risk in horse racing. However, I am confident the course changes we are announcing today will, over time, have a positive impact. We will continue to monitor this carefully and make further improvements and modifications to the course if required as part of our ongoing commitment to safety." Jamie Stier, Director of Raceday Operations and Regulation for the British Horseracing Authority, said: "These modifications are sensible and balanced. Aintree, our team of Course Inspectors and our Senior Veterinary Advisor have analysed DVD footage of races and fallers over the National Course since 2000. We have also received a lot of valuable feedback from our sport's participants and welfare groups. I truly believe it all makes for a strong package of track changes that will enhance rider and equine welfare." The modifications to the Grand National Course announced are: 1. The landing side of Becher's Brook will be re-profiled to reduce the current drop by between 10cm (4 inches) and 12.5cm (5 inches) across the width of the fence. This will provide a more level landing area for horses. 2. Levelling work will also be undertaken on the landing side of the First fence to reduce the current drop and provide a more level landing. 3. The Fourth fence will be reduced in height by 2 inches to 4 foot 10. It was identified during the review that fence Four and fence Six (Becher's) were statistically more difficult to jump than other fences in all races over the National fences and this is the reason for this change. 4. The height of toe boards on all National fences will be increased to 14 inches (36cm). Toe boards are the orange board, positioned at the base of the fence and provide a clear ground line to assist horses in determining the base of the fence. The BHA has launched a wider review of all operational aspects of the 2011 John Smith's Grand National in April 2011, which is ongoing. The Review aims to explore all available options to reduce manageable risk to horses and riders in the world's most famous race. The results of the full review will be published in October.
