Horses in Training is an institution in racing - an indispensable tool for every racing enthusiast.

Compiled in an easy-to-follow style, it is an encyclopaedia of invaluable information on the horses each trainer has in their care, with between 17,000 and 20,000 horses and more than 500 trainers. The book lists alphabetically British, Irish and French trainers, their horses with owner and breeding, foaling dates of two-year-olds and the trainer's contact details.

Fully indexed and numbering around 656 pages, it includes 125 pages of key statistics, covering everything from big-race winners to trainer and jockey tables, fixtures and racecourse information. The book is edited by Graham Dench, a former Racing Post senior reporter and form book editor.
