So you’re front crawl is awesome and your endurance off the chart. But you need to prepare for a few more surprises open water can spring on you.

  • Practise swimming in a straight line. Close your eyes while swimming and see whether you veer left or right (most people do). Try tweaking your stroke to straighten your natural line.

Treading water

  • Most events will involve turning around a marker buoy, often four or five times a race. If you have space in the pool and a willing practice-mate, swim up to and round your friend without touching the walls or bottom of the pool.

Breathing both ways

Group swimming

  • Lots of people swimming together can come as a bit of a shock the first time you swim in an open water event. Practise group swimming with four or five of your friends in one lane of the pool to help get used to the feeling.
