2007 World Thoroughbred Racehorse Rankings
The 2007 World Thoroughbred Racehorse Rankings is the 2007 edition of the World Thoroughbred Racehorse Rankings. It is an assessment of racehorses which was issued by the International Federation of Horseracing Authorities (IFHA) in January 2008. It includes horses aged three or older which raced or were trained during 2007 in countries where the flat racing year runs from January 1 to December 31. These countries are generally in the Northern Hemisphere. The ratings represent a weight value in pounds, with higher values given to horses which showed greater ability. It is judged that these  weights would equalize the abilities of the horses if carried in a theoretical handicap race. The list includes all horses rated 115 or above, and it also shows the surface and the distances at which the rating was achieved. The highest rating in the 2007 season was 131, which was given to the performance of Manduro in the Prince of Wales's Stakes. In total, 212 horses were included in the list, 32 more than in the 2006 Rankings. Full rankings for 2007. Certain horses may have also recorded a lesser rating over a distance different from that listed above . The IFHA publishes this information when the lower rating represents the overall top performance in a particular category. There were three such additional ratings for this season: Top ranked horses. The tables below show the top ranked horses overall, the top fillies and mares, and the top three-year-olds in the 2007 Rankings. They also show the top performers in various subdivisions of each group, which are defined by the distances of races, and the surfaces on which they are run. The IFHA recognizes five distance categories — Sprint, Mile, Intermediate, Long and Extended — identified by the acronym "SMILE". These  are framed as follows:
