Stopping Your Watch

you need to go buy the official running rulebook. it covers everything you must do and must not do for all workouts.

that will answer all your questions.

There's a rule about jogging in place at a stop light.

Actually, if you go for a jog wearing a fanny pack, speedos and you jog in place at stop lights your basically killing three birds with one stone (so to speak).

I believe that the same rules apply to training as for racing. If you are tired, or you have to go for a bathroom stop, then stop your watch. No-one will count that against you in a race. Just start the watch again after you have caught your breath, and/or finished your pit stop, and see what the time is at the end. I have run several three minutes miles in this manner.

If you jog in place and your heart rate remains high, you can keep the watch running.

Otherwise, stop it.

just run

Go by feel... not your watch.
