During the persistence hunt an antelope, such as a kudu, is not shot or speared from a distance, but simply run down in the midday heat. Depending on the specific conditions, hunters of the central Kalahari will chase a kudu for about two to five hours over 25 to 35 km (16 to 22 mi) in temperatures of about 40 to 42 °C (104 to 108 °F). The hunter chases the kudu, which then runs away out of sight. By tracking it down at a fast running pace the hunter catches up with it before it has had enough time to rest in the shade. The animal is repeatedly chased and tracked down until it is too exhausted to continue running. The hunter then kills it at close range with a spear.
