Aintree's Grand National a true test of equine stamina

Aintree's Grand National Steeplechase is a true test of equine stamina. Vieux Lion Rouge is the favourite for the race. The distance and speed of the course can put horses under immense strain. Some of this year's leading contenders have already been pulled from the event. The race is held between the Cheltenham Gold Cup and the Grand Nats. It is common for horses to be rested between these two events. However, Synchronised broke his leg at Becher's Brook at the 11th fence. There are improvements to the Aintrees' course since the past.
