Given that the run is the final section of the triathlon, you will necessarily be fatigued by the time you get to it, and you must have trained your body to run through that fatigue. This is where brick sessions (see Chapter 9) come into play.
On your runs, you should strive to maintain short strides to avoid overstriding and heel striking. Don’t jerk your head up and down with each step – pretend there is a glass of water sitting on top of it. Your hands should be relaxed and not balled up into fists; one technique to correct this is to run with your thumb lightly pressed against your ring finger. Hands should stay on their side of the body and not cross over the belly button. Keep your arm swing small. Think, “nips to hips.” Keep a strong core and stay upright, even when you get tired.
