In order to swim in a triathlon, according to Jodie Swallow‚Äôs technique, you will need an efficient stroke. You will need to work on your turn over. Try to aim for 90 strokes per minute. Rhythm, flow, and momentum are key. You will want to find your rhythm and keep it throughout. Timing is important. Breathe at the same point of each breathing stroke. Flex your wrist to improve your feel of the water and your momentum. Try to keep your elbows high and bent, when in the under water portion of your stroke. Your strokes should look punchy. Try to eliminate dead spots in your stroke and overreaching. Eliminating these problems will increase your stroke rate.
