ワールド・サラブレッド・ランキング
The Longines World's Best Racehorse Rankings (LWBRR), known as World Thoroughbred Racehorse Rankings (WTRR) before 2012, are horseracing's equivalent to World Rankings by other major sporting organizations such as ATP Tennis Rankings, World Golf Rankings, FIFA World Rankings for soccer and IRB Rugby World Rankings. The Longines Rankings are based on the rating earned by horses running worldwide from North and South America, Europe, Middle East, South Africa, Asia through to Australia and New Zealand.
