For their size, giant pandas are pretty fast, averaging 20 miles per hour at top speed. When walking, pandas typically lumber along at speeds of 1.2 to 1.8 miles per hour and travel less than 0.62 miles per day, usually only moving around while foraging for food.
The giant panda can weigh anywhere from 242 pounds to 551 pounds, which makes it quite the feat that it can actually move as fast as it does. Healthy adults have no natural predators, so they have little need to run. Ill, injured or young pandas may be preyed upon by leopards and some birds of prey, however.
