01 Frontal breathing
Every 3-4 breaths, do a frontal breathing. It will let you orientate and avoid deviations.
02 Buoys as references
Use buoys as references in your route. You can also use it to train by intervals.
03 Bilateral breathing
Train with assiduity in pool and try to improve your bilateral breathing (both sides breathing). It will let you breath in the best side that sea offers to you.
04 Study water movements
Sea conditions are never the same. Take your time and study water movements, waves and most dangerous areas before enter.
05 Train your strokes and your feet efficiency
In the sea, your buoyancy is higher than in the pool. Train your strokes and your feet efficiency to fatigue less.
