Running, especially on campus, is so tiring but good exercise. It's a form of terrestrial locomotion.
I cannot say that I'm a fan of running - unless a bear is chasing me!  Do you know who started running as exercise?  I mean, it seems someone must have been crazy!

I like walking - much less jarring motion.  And I don't think you need the fancy shmancy running shoes either.  And most anyone can walk - well except those that can't of course.  What do you know about running in the Olympics?

Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.
