The dromedary camel has long, powerful legs with large two-toed feet which have soft thick and flexible footpads. These enable them to easily walk on soft sand and gravel but they provide little traction on slippery and muddy surfaces. Unlike most animals, camels move both legs on one side of the body at the same time (lift both left legs - lift both right legs, rather than one left and one right leg like most other animals). The walking stride is long and slow, with the body supported for much of each stride on the grounded legs on one side of the body. Camels can run at 40 kph for extended periods of time and can sprint at 67 kph for short periods.
