In 2004, the Racing Post asked its readers to nominate their three favourite racehorses. Horse racing's bible was not interested in which horses its readers considered to be the greatest in terms of merit. Rather, they wanted to find out those which meant the most to its readers. Over two months, thousands of votes were collected. From the nominations was compiled this definitive list of the 100 most popular horses of all time to race in Britain and Ireland - on the Flat and over the Jumps.
