Longines World's Best Racehorse Rankings The Longines World's Best Racehorse Rankings are an international assessment of Thoroughbred racehorse performance compiled annually by the International Federation of Horseracing Authorities. They rate horses that competed in flat racing events across jurisdictions including the United Kingdom, United States, Ireland, France, Australia, Japan, Hong Kong, and United Arab Emirates. The list is used by owners, trainers, breeders, and media such as BBC Sport, The New York Times, Daily Telegraph, and Sky Sports to compare elite performers from different racing jurisdictions and seasons.
Overview
The rankings provide a numerical rating for individual horses based on peak performances in major races such as the Prix de l'Arc de Triomphe, Breeders' Cup Classic, Melbourne Cup, Japan Cup, Kentucky Derby, Dubai World Cup, and Epsom Derby. Administered by the International Federation of Horseracing Authorities, the project involves handicappers and rating officials from constituent bodies including the British Horseracing Authority, American Graded Stakes Committee, Racing NSW, Japan Racing Association, and the Hong Kong Jockey Club. Sponsors and partners have included Longines, Daily Mail, and international broadcasters like NBC Sports and ITV Racing.
History and development
Origins trace to the 1977 International Classification, an initiative by the International Federation of Horseracing Authorities and national authorities including the Jockey Club and the Irish Horseracing Regulatory Board. The system evolved through collaboration with handicapper groups from the France Galop, Deutscher Galoppverband, and the Stud Book authorities. In 2012 the rankings were relaunched with title sponsorship by Longines and expanded methodology influenced by statistical research from institutions such as University of Oxford and consultants with backgrounds linked to the Racing Post and Timeform. Over decades the list has reflected shifts caused by globalization of racing, with increasing participation from stables like those of Aidan O'Brien, Bob Baffert, Godolphin, Coolmore Stud, and owners such as John Magnier and Sheikh Mohammed bin Rashid Al Maktoum.
Methodology and criteria
Ratings derive from expert handicappers who assess performances in Group/Grade 1, Group/Grade 2, and other significant stakes races including the Queen Elizabeth II Stakes and St Leger Stakes. The panel includes representatives from the British Horseracing Authority, Japan Racing Association, Australian Racing Board, UAE Racing Federation, and the American Graded Stakes Committee. Key criteria encompass weight carried, finishing margin, quality of opposition (e.g., winners of Breeders' Cup Turf or Preakness Stakes), and race conditions at venues like Ascot Racecourse, Churchill Downs, Meydan Racecourse, and Flemington Racecourse. Statistical adjustment techniques reference models used in publications by Timeform and academic analyses appearing in journals such as the Journal of Sports Analytics.
Annual rankings and notable winners
Each year the top-rated horses are often winners of premier events: past honorees include champions like Frankel (horse), Sea The Stars, Winx, Arrogate, Zenyatta, Enable (horse), Gold Ship, and American Pharoah. The 2016-2017 era featured horses campaigned by trainers Sir Michael Stoute, Aidan O'Brien, Chris Waller, Todd Pletcher, and Yutaka Take. Winners have influences on breeding markets at institutions such as Keeneland, Fasig-Tipton, Windsor Park Stud, and Coolmore Stud, and affect stallion fees involving sires like Galileo (horse), Tapit, Deep Impact, and Dubawi.
Impact and reception
Breeders, owners, auction houses, and media outlets including Racing Post, BloodHorse, Thoroughbred Daily News, and The Australian use the rankings to inform stud valuations, syndication deals, and breeding decisions at venues like Newmarket, Flemington, and Kildangan Stud. National racing authorities cite rankings in promotional materials for events such as the Breeders' Cup World Championships, Melbourne Cup Carnival, and the Dubai World Cup Night. Betting markets and bookmakers such as Bet365, William Hill, Ladbrokes, and Paddy Power monitor ratings when setting markets for international fixtures.
Controversies and criticism
Critics from publications like The Guardian, Racing Post, and commentators associated with Timeform have raised concerns about subjectivity, transparency, and potential bias toward jurisdictions with larger Group 1 calendars such as Europe and North America. Disputes have arisen over ratings assigned to horses trained by high-profile stables including Godolphin and WinStar Farm, and over treatment of form from racing surfaces at tracks like Ascot Racecourse versus Kawasaki Racecourse. Academic critiques in outlets like the Journal of Equine Science question reproducibility and advocate for greater statistical disclosure and peer review.
Comparison with other rankings
The Longines list is frequently compared with private and media-based systems including Timeform ratings, the Racing Post Ratings, the Equibase Top 100, and various national handicaps like the BHA Official Handicap and the Japanese Racing Association official ratings. Differences stem from panel composition—with representatives from bodies such as the American Graded Stakes Committee and France Galop—and methodological emphasis on peak single-race performances versus season-long consistency favored by some media lists used by Daily Telegraph and The Sporting News.
