Having the ability to breathe bilaterally, on both the left and right side of your body, is a very useful skill to have. 

From a technique perspective, bilateral breathing can help to alleviate some common errors, make your stroke more symmetrical and even out any imbalances. Depending on your effort level you may also need to breathe more frequently when your body needs to take in more oxygen.

It becomes increasingly beneficial when you transition from the pool to open water. If the conditions are particularly choppy and you go to breathe on one side, but you get hit by a wave, you can keep going and breathe on the opposite side away from the chop. Similarly, if you are surrounded by other swimmers who are causing a splash you can breathe on whichever side is clearer. It can also help with sighting – crucial in open water when there is no black line along the floor to follow! You can be more aware of your surroundings when breathing/looking both ways; keeping an eye on the shoreline, spotting the next turn buoys, or ensuring you aren’t drifting away from all other competitors.

Throughout your training spend some time practicing breathing on both sides. Incorporate breathing drills into your warm up or main sets where you breathe every 2nd, 3rd, 4th, 5th stroke. The more you practice the more relaxed you’ll be come race day.
