Dog In A Jogging Suit

The definition of jogging as compared with running is not standard. Dr. George Sheehan, a running expert, is quoted to have said "the difference between a jogger and a runner is an entry blank". Mike Antoniades offers a more specific definition, describing jogging as running slower than 6 mph (10 minute per mile pace, 9.7 km/h, 6.2 min/km).
History
In 1593 William Shakespeare wrote in Taming of the Shrew, "you may be jogging whiles your boots are green"; the word green meaning 'new', thus, jog when you are fresh, or when you are most ready or able.
