They are the second fastest animal on land and can reach speeds of up to 60mph, nearly as fast as the cheetah. This is fast enough to outrun their main enemies, wolves and coyotes. Although the pronghorns are faster, the wolves and their cousins have stamina on their side, enough to run down young and weak adults.

These antelopes can weigh 70kg.
Like other antelopes, pronghorns migrate.
