Running: 5 more tips to stay motivated

11. FILL THE TUB with hot water, then head out for a three-miler on a frigid morning. The sooner you get back, the hotter your bath is.

12. EVERY MILE YOU RUN burns roughly 100 calories. Think of that next six-miler as two slices of pizza.

13. RUNNING COMMENTARY "No one can say, 'You must not run faster than this or jump higher than that.' The human spirit is indomitable." --Sir Roger Bannister, the first man to run a sub-four-minute mile

14. READ THIS The Loneliness of the Long-Distance Runner, a short story by Alan Sillitoe, tells the tale of a rebellious youth in a reformatory who runs in solitude and makes a stand against a system he doesn't believe in. You'll have new appreciation for the power of solo runs.

15. PLAY IN THE STREET. Skip a dreaded track workout for a fartlek (Swedish for "speed play") session. After 10 minutes of easy jogging, run hard between two telephone poles, then slow down until you pass three. Then see if you can get to the traffic light before it changes, followed by a jog to the next mailbox. There are no set rules, so make it up as you go along.
