An acronym for Techniques de Randonnée Équestre de Compétition. Discipline born at the end of the 1980s, the TREC, close to Competitive Trail Riding, is inspired by the difficulties which may be found when out trekking. These events aim to assess the rider and his/her horse over an orienteering and regularity course, a race on a varied field (ford, hedge, stairs, etc.), a presentation of the pair (good harness) and a mastership of the paces.
