How fast can a pronghorn antelope run in meters per second? ... Antelope Speed=107360yards /(3600 seconds)=29.822 yards/second. Relative to their small stature, pronghorn have a large windpipe, heart and lungs, making them extraordinarily fast. About 2900 acres of land were jointly purchased by the two organizations and subsequently turned over to the Biological Survey as a pronghorn refuge. [37] Before fighting, males try to intimidate each other. The top speed is dependent upon the length of time over which it is measured. [27] Some female bands share the same summer range, and bachelor male bands form between spring and fall. Although first seen and described by Spanish explorers in the 16th century, the species was not formally recorded or scrutinized until the 1804–1806 expedition by Captain Meriwether Lewis and Second Lieutenant William Clark.
