RAID- T.R.E.C. is presented as a new discipline that combines the most outstanding characteristics of the two aspects that give it its name. On the one hand, they take from the T.R.E.C. the need for simple orientation from the map, the presence of secret controls and the pre-determined speed. On the other hand, the RAID provides the distances (20km, 40km, 60km, 80km and 100km), the highest speeds and the agility of the competition. The result is a competition of mental agility and physical and psychic endurance on the part of the binomial in which rider and horse will have to face the difficulties posed by the tracers and possible weather adversities.
