Marianna Haun’s Understanding the Power of the X Factor unlocks the genetic secret many trainers believe gives Thoroughbreds that unbeatable edge on the track. This 2001 paperback blends animal science with racing strategy, explaining how the elusive “X factor” can be spotted in conformation, pedigree, and performance.
Ideal for adults and young adults passionate about horses, the book moves from basic equine anatomy to professional handicapping tips, making it a favorite among owners, breeders, and hobbyists who want more than luck guiding their bets. Clean, tight pages mean no prior notes distract from the diagrams and pace charts that pepper the 253-page guide.
This very good copy shows only light shelf rub to the cover and a few dark scuffs atop the page block—minor cosmetic wear that keeps the price friendly while the content stays razor-sharp. Stored smoke-free, it’s ready to slip into a racing library or accompany you to the morning workouts.
Add Haun’s respected reference to your collection and start reading the horse, not just the odds.
