Built like a form book.

A horse's official rating is the surface. Underneath sit the attributes that produce it — speed, stamina, acceleration, balance, temperament — plus preferences for trip and ground that the form book only hints at. Training shapes the horse over time: bring fitness to a peak for a target, back off a fragile type, and learn each animal's character run by run. Two horses with the same rating can be entirely different problems.

More than two hundred races across a complete British flat season, with valuable prizes in Ireland and France for yards ambitious enough to travel. Maidens, handicaps, listed races, group races and the season's defining prizes — each with entry and declaration deadlines that force real commitment. The calendar is where strategy lives: campaign a horse patiently toward autumn, or strike while a division is weak.

Owners arrive with silks, budgets, personalities and expectations. Manage the relationship as carefully as the horse: honest placement builds trust, results build patience, and a good reputation brings better bloodstock to your door. Lose an owner's confidence and you may watch their best horse win for a rival next season.

Retire mares to the paddocks, stand your champions at stud, and plan coverings that won't pay off for years. Foals inherit from both sides of the pedigree and still manage to be themselves. Buy and sell at the sales, build families across generations, and chase the rarest thing in the game — the homebred that changes everything.

Rival trainers buy, develop, place and retire their own strings, each with a recognisable style. Champions emerge from other yards and retire to stud where their offspring keep the story going. Records, honours boards and championship tables persist across seasons — a racing world with its own history, whether you're part of it or not.

Give the instruction and watch the race unfold — pace, position, ground and trip all matter, and the in-running comments tell you why. Results feed straight back into the form book, official ratings, prize money and reputations. A race lasts two minutes. Its consequences can last a career.
