Why Distractions Make You Slow

We got a great question on the forums about constantly changing your swim route in a race that made me think about this video -

Notice there's no "The more you know.." NBC jingle at the end of this bad motherf*cker.  Cavendish is not making a PSA for little kids.  This is about a subject that elite athletes have mastered.  And Cavendish wins.  He wins A LOT.  He focuses on the kill and doesn't spend any time debating on if he should or shouldn't change course.  

Which leads me to this little blog post I found today.  I twittered it and was not surprised to find lots of people loved it.  They love it because, deep down, it rings true and we know it.

The next time you go out for a workout, remember that pain is a symptom of performance.  If you want to improve, you better be willing to put in the effort.
