Timeform

Timeform Publications is a publishing company 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.

History

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.

Data system

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".
