César Tasias, a very experienced endurance rider, began competing in endurance when he still was a child, on his father's side, also a big enthusiast of this sport. César's large experience and important career in the high competition brought him to develop into trainer not only of his own horses, but also from the ones from other competitors.

The study and consideration of each horse, the observation of its qualities and possible disadvantages, allow Tasias to design the personalised training.
