Speed Figures in Horse Racing — Beyer Numbers, Timeform Ratings and How to Use Them
Speed figures convert raw race times into a standardised rating that accounts for track conditions, going, and distance — allowing direct comparison of performances from different tracks, distances, and conditions. Beyer Speed Figures (US) and Timeform ratings (UK/global) are the two dominant systems.
Why Raw Times Don't Tell the Whole Story
A horse running 1¼ miles in 2:01 at Churchill Downs on a fast dirt track is not directly comparable with a horse running 1¼ miles in 2:04 at Saratoga on a good-to-firm turf — the distance is the same but the surface, track configuration, and conditions are completely different. Speed figures address this problem by converting raw times into a standardised number that accounts for these variables, creating a single performance rating that can be compared across different tracks, surfaces, and conditions. A horse that earns a Beyer Speed Figure of 105 at Churchill Downs has run equivalently to a horse that earns a Beyer of 105 at Santa Anita — despite different actual times on different tracks.
Beyer Speed Figures: The US Standard
Andrew Beyer's speed figure methodology, developed in the 1970s and published in his book Picking Winners (1975), became the definitive US speed figure system and is now published in the Daily Racing Form for every US race. Beyer figures are adjusted for two variables: the variant (how fast or slow the track was running on a given day, calculated from the entire day's racing) and the par time (the expected time for a horse of average quality at that distance and class level at that track). A Beyer of 100-110 represents stakes-quality performance; 80-90 is solid handicap class; 60-70 is typical maiden/claiming level. The Beyer figure is the single most-consulted number in North American racing form analysis — a horse improving its Beyer by 10+ points in a single run is a significant positive signal; a horse declining 10+ points is worth investigating.
Timeform Ratings: The Global Standard
Timeform was established by Phil Bull in 1948 and remains the world's most widely used independent ratings system, operating across UK, Irish, US, Australian, and international racing. Timeform ratings are not pure speed figures — they combine time analysis with 'eye' assessment (how well or badly a horse was judged to have run visually), making them a composite performance rating that incorporates both raw performance data and analytical judgement. Timeform ratings are expressed on a scale where 100 represents a decent handicapper, 130+ represents a top-class Group 1 horse, and the all-time highest ratings belong to legendary horses (Frankel's Timeform peak of 147 is the highest ever assigned to a flat horse). The 'p' symbol (potential) indicates a horse Timeform believes can improve significantly; the 'P' (capital, or 'big P') indicates exceptional potential.
Racing Post Ratings (RPR)
Racing Post Ratings are the UK-focused equivalent of Beyer figures — a numerical rating assigned to each horse's performance that can be compared across races, tracks, and conditions. RPRs are calculated using a similar methodology to Timeform (combining time data with analytical assessment) and are published in the Racing Post form guide. For practical betting purposes, RPR and Timeform serve similar functions — both allow direct numerical comparison of performances. The key difference: Timeform is more conservative in assigning high numbers to horses that haven't proven their quality in multiple high-quality races; RPR is more responsive to individual performances. Neither should be used mechanically — a horse that earns a high figure once may not reproduce it.
How to Use Speed Figures in Betting
Speed figures are most valuable when used to identify horses that have been running faster than the market recognises — either because the figure is from a track or country where form is less well-known, or because the horse ran a fast figure in a race that looked unimpressive visually. Key usage tips: (1) Look for consistent high figures, not just one peak performance. (2) Check for figure improvement trends — a horse whose last three figures are 85, 91, 96 is on a trajectory that may justify favouritism even if not the highest-rated horse on raw form. (3) Account for surface changes — Beyer figures are track-specific; a horse's dirt figures don't translate to turf figures. (4) Combine speed figures with going preferences — a horse that earned its best figure on fast ground may not reproduce it on soft ground even if its form otherwise looks good.
