Timeform is a sports data and content provider located in Halifax, West Yorkshire, England founded in 1948 to provide information to fans, bettors, and others involved in the horse racing industry. The company was purchased by the sports betting exchange Betfair in December 2006. Since 2 February 2016, it has been owned by Paddy Power Betfair.
Portway Press Ltd was formed in 1948 by Phil Bull, who wanted to establish a mathematical link to a horse's performance, based on the time the horse recorded. At a time when such data was virtually unheard of, Bull started publishing a racing annual, which evolved into the "Racehorses Of.." series. The company was purchased for a reputed £15 million by the sports betting exchange Betfair in December 2006.
According to the publishers, a Timeform rating represents "the merit of the horse expressed in pounds and is arrived at by careful examination of its running against other horses using a scale of weight for distance beaten which ranges from around 3 lb a length at five furlongs and 2 lb a length at a mile and a quarter to 1 lb a length at two miles".
The Beyer Speed Figure used in the United States is similar to a Timeform rating. The popular rule of thumb for comparing these two numbers is to add 12–14 points to the Beyer score to estimate the Timeform number.
Timeform ratings for 3-year-olds and up are as follows:
Timeform states that 2-year-old averages are slightly lower.
The Daily Racing Form gives an example of the evolution of ratings for horses from age two upwards in the American Grade I Arlington Million.
Timeform maintains different scales for horses racing on the flat, over hurdles and over fences. The scores cannot be compared for the obvious differences between the race types. For instance, Arkle at 212, Flyingbolt at 210, Sprinter Sacre at 192 are then followed by Mill House and Kauto Star, both at 191, are the highest rated steeplechasers. The highest rated horses over hurdles are Night Nurse at 182, Istabraq and Monksfield, both at 180, and Persian War at 179. The table below lists scores for flat horses only starting with the highest, rated at 147 which is the British horse Frankel.
