How fast does an orangutan run on foot?

Orangutans are not built for running on foot like some other primates; they are primarily arboreal and adapted for life in trees. However, when they do move on the ground, they can reach speeds of about 2 to 3 miles per hour (3 to 5 kilometers per hour). Their locomotion is generally more about walking or ambling rather than running, as their long arms and strong upper bodies are better suited for climbing and swinging through branches.
