In the first stages of taming, only the individuals that show the stamina, courage, health and good heart recovery - all essential conditions to compete in the demanding endurance racing - will start specific training to become long-distance endurance horses. In the slow and careful process of training, the horse begins on the shortest distances and at the easiest speed. These marks are gradually increased and successfully reached, respecting the necessary rests, before we consider a horse as totally prepared for real competition. When training and competing, our main goal is to form our young horses for sport competitions. 
Each horse is trained respecting individual characteristics. The training levels are increased gradually according to the improvement in its physical condition. The idea is that during its first competitions, the young horse will learn about the sport, such as to leave home, get on a truck, stay in unknown barns, be among many unknown horses, be in a crowd of people, and change from the quiet training it was used to, into racing in a big group of horses, etc. It is not speed what we seek at this stage, but a young horse with the least possible stress in this new activity. Following the rules of the FEI (Federation Equestre Internationale) we increase the distances until 120km in a period of two years, always doing some repetitions on each distance to let the horse get adapted. After this and only with the horse in perfect conditions, we look for the speed. We consider it often important to give young horses a break in their training for a few months, to relax from the sport's high physical demands.
