Aintree director on Grand National changes
- From the section Horse Racing
Julian Thick, managing director of Aintree Racecourse, tells BBC Sport's John Sinnott that the changes to the Grand National course will not change the race's character.
The course for 2012 will be altered after a review of April's race in which two horses were fatally injured.
Thick believes the changes are "positive safety measures" and will improve the race.
