运动员热身区:副跑道与器材暂置

Show the warm-up area behind the main stand of an athletics stadium, a working space rather than a display one. Render a short straight practice track of four lanes in the same brick-red surface, about 120 metres long, running parallel to the main stadium wall with a strip of grass alongside. Detail the space as busy and cluttered in a functional way: hurdles stacked in rows by height, starting blocks lined up on a trolley, a rack of throwing implements, foam rollers and mats spread on the grass, and bags dumped along a low wall. Show athletes in tracksuits doing drills, stretching, and one set of blocks in use with a coach crouching alongside holding a stopwatch. Include a call-room tent with a folding table and a clipboard, a marshal with a numbered board, and a water station with paper cups. Detail the boundary as a chain-link fence with green windbreak fabric separating this area from the public car park. Show bright pre-event morning light. Photorealistic, busy, functional, eye-level view along the practice straight.
