In a handicap race, the horses carry different weights according to their quality. Faster horses are given greater weights to carry, such that all horses should cross the finishing line very close together. The Grand National is a handicap race.
Owning, breeding and training thoroughbred horses is still a favourite preoccupation of monarchs and the wealthy. A winning horse can increase dramatically in value and be sold for profit. However most horses cost more to maintain than they win or earn from stud fees.
