Longer pieces on the built and designed side of sport — venues, surfaces, equipment and the decisions embedded in them.

Features
A strung net always dips in the middle. Tennis decided to make the dip 156 millimetres and mandated a strap to produce it; badminton lets it be 26; volleyball forbids it and allows 20 millimetres of error. One physical fact, three regulatory answers.
Features
The UCI fixes a track's length, its width, the position of three painted lines and the requirement that any cross-section be straight. It does not fix the banking, does not require the four quadrants to match, and the resulting geometry is often withheld as commercially confidential.
Features
FIS will not sanction a race on ground it has not homologated, and the dossier it requires is a portrait of what a venue has to be. Gradients and vertical drop take a few lines. Evacuation, water supply, uphill transport and cable runs take the rest.
Features
A track is specified by how much force it swallows and how far it sinks, not by how well it grips. Both numbers have an upper bound as well as a lower one, and that is the whole design problem: a surface springy enough to give energy back is soft enough to waste it.
Features
Wood set the limits of a tennis frame more strictly than any rulebook did. When composites removed them, head size, stiffness and string-bed behaviour all moved at once — and the two-handed topspin backhand became the cheaper answer.
Features
A competition pool has one hydraulic job: to take back the energy eight swimmers pour into it and not give any of it back. Depth, lane ropes, lane width and the gutter are four different exits for the same waves.
Features
A padel ball and a tennis ball are almost the same object. The ground they are hit on is not — because two of these sports decided that a boundary should return the ball instead of ending the point.
