Every racehorse has its trainer. Sometimes, trainers are also owners.
Trainers are responsible for the wellbeing, training and feeding of the horse.
Furthermore, they decide in which races the horses will compete and which races they are more likely to win.
Finally, the trainers inform the owner on the progress of the horse.
At the races, the trainers supervise the final preparations and consult the jockeys regarding the strategy they shall follow in order for the horse to have the best possible performance.
Sometimes in order to decide their strategy they even walk the track to see its state and how they can use it to their advantage.
