World Aquatics rulebook swimming — four strokes, a pace clock, and the gap between a club heat and an Olympic final. Competitive swimming is the measured, judged version of pool swimming: four strokes, relays, and a clock that records to hundredths. World Aquatics (FINA until 2022) writes the rulebook that clubs, schools and the Olympics share.
Most of the world’s racing happens in short-course 25-metre halls, not in Olympic finals. The skill ceiling in this atlas is high because technique, training load and race craft stack for a decade. Risk stays low relative to wreck or night diving: the hazards are overuse and the rare shallow-water dive, not current.

This chapter is a club-sport map, not a governing-body medical screen and not a live meet brief. Memberships and qualifying times belong to national federations. More walls in a 25 m pool mean more push-offs. World Aquatics keeps separate short-course and long-course lists.
Textile suits with coverage rules replaced the 2008–2009 polyurethane spike. National bodies publish the current approved list. No. Triathlon swimming is open-water, usually wetsuit-banded, and ends in a transition. Pool racing is stroke-legal and wall-based.
