Ratings The handicap ratings of all horses are compiled by the British Horseracing Authority Handicapping team and stored on Weatherbys’ computer (Weatherbys do all the administrative work for the British Horseracing Authority).
Every time a horse runs, the handicapper must decide whether or not to amend its rating. Each week all such amendments, made after the evaluation of the results of all races run between Sunday and Saturday inclusive, must be transmitted to Weatherbys by 7.00 the following Tuesday morning.
Visit our handicapping page for more information about how the system works.
