In what year was the Grand National horse race declared void?

The 1993 Grand National (officially the Martell Grand National Chase Handicap Grade 3) was scheduled on 3 April 1993 to be the 147th running of the Grand National horse race, held annually at Aintree Racecourse near Liverpool, England.

It was the first and so far only time that the steeplechase was declared void, after 30 of the 39 runners began and carried on racing despite there having been a false start. Seven of the field even went on to complete the course, with Esha Ness crossing the finishing post first, in what would have been the second-fastest time ever.

The Jockey Club decided not to re-run the race, and as a result it has often been called the race that never was. Bookmakers were forced to refund an estimated £75 million in bets staked. The Jockey Club launched an inquiry which led to a number of changes in the starting and recall procedures in future races.
