I don't really walk or run. But I actually think that walking, through nature is generally the center of the mental universe. Or at least the thing that can create chemical homeostasis in the brain. Everything about humans from an evolutionary standpoint is improved towards walking through a forest type environment. There is some research that shows lateral movements in the periphery of the eye, such as what occurs at walking speed, reduces chemicals that cause stress/anxiety/depression. It also only seems to work in a very natural environment, indoors, manicured walking tracks or city streets don't have the same impact, but it can be simulated with monitors / VR. So perhaps VR nature walking on a treadmill would be a panacea for many mental issues brought on by modern stress.
