Despite the name Pacu Jawi (literally 'bull race' or 'cow race' in Minangkabau), this is not a direct competition between animals. Each rider chooses his two best cows for the "team". Then he puts on a harness (ropes) and stands on a wooden plow connecting them, which has two functions. First of all, it creates a platform, unstable and not very comfortable, for a daredevil participating in the race. Secondly, it prevents animals from separating on the route. Animals are usually bulls between the ages of 2 and 13 whose run in pairs.
