Guide

A complete guide to the main table above.

Rank

A horse's position in the list, with the most highly rated at number 1. Each horse is ranked once according to its highest rating. Any lesser ratings for the same horse are not ranked.

Rating

A rating represents a weight value in pounds, with higher values given to horses which showed greater ability. It is judged that these weights would equalise the abilities of the horses if carried in a theoretical handicap race. The minimum rating required for inclusion is 115.

Horse

Each horse's name is followed by a suffix (from the IFHA's International Code of Suffixes) which indicates the country foaled.

Age
The age of the horse at the time it achieved its rating. The racing ages of all horses foaled in a particular part of the world increase simultaneously, regardless of the actual date of foaling.
Dates of age increase by location foaled
Northern Hemisphere	1 January
South America	1 July
Australia, New Zealand and South Africa	1 August

Sex
C	Colt	Ungelded male horse up to four-years-old
F	Filly	Female horse up to four-years-old
H	Horse	Ungelded male horse over four-years-old
M	Mare	Female horse over four-years-old
G	Gelding	Gelded male horse of any age

Trained

The country where the horse was trained at the time of the rating, abbreviated using the International Code of Suffixes.

Position
The horse's finishing position in the race shown. The actual finishing order can sometimes be amended following an inquiry or a disqualification.
=	Dead-heat
↑	Promoted from original finishing position
↓	Relegated from original finishing position

Race

The race (or one of the races) for which the horse achieved its rating. A defeated horse can be rated above its higher-placed opponents if it carried more weight.

Surface

The surface of the track on which the race was run, eg. turf or dirt. Synthetic surfaces are described as "artificial".

Distance
The distance of the race in metres. In some countries (eg. Canada, Great Britain, Ireland and the United States), the length of a race is usually expressed in miles and furlongs. These units have been converted to metres to allow for universal comparison.
Common conversions
5 furlongs	= 1,006 m	1 mile and 1½ furlongs	= 1,911 m
6 furlongs	= 1,207 m	1 mile and 2 furlongs	= 2,012 m
6½ furlongs	= 1,308 m	1 mile and 2½ furlongs	= 2,112 m
7 furlongs	= 1,408 m	1 mile and 3 furlongs	= 2,213 m
7½ furlongs	= 1,509 m	1 mile and 4 furlongs	= 2,414 m
1 mile	= 1,609 m	1 mile and 6 furlongs	= 2,816 m
1 mile and ½ furlong	= 1,710 m	2 miles	= 3,219 m
1 mile and 1 furlong	= 1,811 m	2 miles and 4 furlongs	= 4,023 m
