Side stitch: slow down, exhale longer
A sharp side stitch is your cue to ease pace, deepen the exhale (especially on the opposite side of the stitch), and avoid stacking a huge meal or new gel right before hard efforts. If stitches are constant with GI chaos, practice race fuel on easy long runs — gut training is a skill. Persistent pain that isn't a stitch deserves a clinician, not another YouTube stretch.
