Grand National in front of the stands. The majority of the race therefore took place not on the actual Aintree Racecourse but instead in the adjoining countryside. That countryside was incorporated into the modern course but commentators still often refer to it as "the country". There are 16 fences on the National Course topped with spruce from the Lake District. The cores of 12 fences were rebuilt in 2012 and they are now made of a flexible plastic material which is more forgiving compared to the traditional wooden core fences. They are still topped with at least of spruce for the horses
National Hunt racing is run over a distance of more than 4 miles, there are up to 40 runners, the course at Aintree is essentially flat, and the horses are handicapped (the best horses carry the most weight). Perhaps the most fundamental difference is that the Grand National fences are far bigger than the fences at Cheltenham, and a number of fences incorporate significant drops. The most famous fence is Becher's Brook which is 5ft high, but has a 7ft drop on landing and is widely regarded as the biggest challenge on the course. Famous winners of the Grand National include Red Rum
