Breathing patterns for every pace

Asymmetric patterns (like 3:2) distribute impact forces evenly between legs, reduce the work of breathing, and act as an internal metronome—helping you lock into a sustainable pace with lower perceived exertion. These rhythms also promote deeper diaphragmatic breaths, improving oxygenation and calming your nervous system under race stress.
