In this type of condition program, the horses are usually trained at slow speeds but longer distances. The sessions usually include trotting and cantering for long distances at slow speeds. Trainers start the horses slowly and progressively increase the distance. The total time a horse can be on such a conditioning program can vary according to the time it has for the event but usually, these programs range from four to five weeks. Such programs are usually taken up by horses who are going to take part in endurance racing events.
