What Is 2021 World's Best Racehorse Rankings

Overview

The 2021 World's Best Racehorse Rankings identify the top-performing thoroughbreds globally based on official handicapping assessments conducted by the International Federation of Horseracing Authorities (IFHA). These rankings reflect performances between January 1 and December 31, 2021, across elite flat races on dirt, turf, and synthetic surfaces.

The rankings are designed to provide an objective, comparative measure of international racehorse excellence, factoring in race class, competition strength, and winning margins. Each horse is assigned a numerical rating, with higher scores indicating superior performance.

• Cryptogram, a Japanese stayer, earned the top rating of 129 after winning the Dubai World Cup and Tenno Sho (Spring).
• Nature Strip from Australia scored 127 due to dominant wins in the VRC Sprint Classic and The Everest.
• St Mark's Bay, trained in France, matched Nature Strip’s 127 after victories in the Queen Anne Stakes and Diamond Jubilee Stakes.
• The rankings included horses from 15 countries, including Japan, Australia, the UK, Ireland, and the United States.
• Only horses competing in Group/Grade 1 races were eligible, ensuring a focus on the highest level of competition.

How It Works

The rankings are determined through a collaborative process involving official handicappers from 11 major racing nations, who meet annually to evaluate performances using standardized criteria.

• Rating System: Each horse receives a numerical score based on race quality, with 120 considered elite and scores above 125 extremely rare.
• International Consensus: Handicappers from 11 countries submit evaluations, and final ratings are agreed upon through discussion and voting.
• Timeframe: Only performances from January 1 to December 31, 2021 were considered for the 2021 rankings.
• Surface Adjustments: Ratings account for differences in track surfaces, including turf, dirt, and synthetic, with adjustment factors applied.
• Group Race Focus: Only results from Group 1 or Grade 1 races are eligible, ensuring consistency in competition quality.
• Weight and Distance: Handicappers adjust scores based on weight carried and distance run, with stronger races yielding higher ratings.
