How the TRC Global Rankings work

  • The TRC Global Rankings are a measure of an individual's level of achievement over a rolling three-year period. 
     
  • They are based not on prize money the individuals' representatives have won but on the quality of the performances those runners have put up in Group and Graded races. There are about 1,450 qualifying races around the world every year.
     
  • An individual’s position in the rankings depends entirely on how well their representatives have been running. Racing Post Ratings (RPRs) are used to help calculate the merit of every performance of every runner in each of the races. 
     
  • Individuals are positioned in the standings according to their total points (bold figure in the second column from the end).
     
  • The points are derived from two numbers - Impact Value (IV) and time-decayed Racing Post Ratings (tRPR) - which are displayed in two columns in the centre of the tables.
     
  • Impact Value is a variation on strike-rate, but it is a much more stable and discerning calculation, measuring the relative strike-rate of an individual taking field sizes into account. (As a rough guide: if you have a 10 percent strike-rate in 10-runner races your IV is 1.00. If you have a five percent strike-rate in these races, IV is 0.50 and, if you have a 20 percent strike-rate, it is 2.00.)
     
  • With tRPRs, we have built in a weighting that means performances count for less as they get older. So a 120-rated performance in 2016 counts for more than it did in 2015, which in turn counts for more than it did a year earlier.
     
  • In general, horses achieve higher marks in the U.S., Britain, Ireland, France, Japan and Australia than they do in some other major racing nations*, like Chile, South Africa and Germany. So their trainers, owners, jockeys and stallions are largely higher in the rankings.
     
  • At present, for example, three of the top five horses in 2016 on Racing Post Ratings are trained in America, one is Japanese and the other is Australian. 
     
  • It should be reasonably easy to understand why individuals are where they are in the tables by comparing the numbers in the IV and tRPR columns.   
     
  • Individuals are listed under ‘Modal Country’, which is the country where they have had the most runners and is not necessarily the one where they are based.
     
  • There is a search facility with each of the categories in the TRC Global Rankings that enables you to find any individual in the top 500, or to isolate the representatives from any modal country into one list.
     
  • You can click on any individual’s name to bring up a complete list of counting runs over the past three years.
     
  • Each of the pages includes a link to a list of all the Group and Graded winners from the previous week (Winners), plus another (Climbers) to a list of the individuals that have gained the most points in the week.
