Create a realistic full-body vertical outdoor sports portrait of an adult female track-and-field athlete standing front-facing against a gray concrete wall with visible seams, small holes, and subtle weathered texture. She has a sturdy, athletic-curvy build with broad shoulders, toned arms, a soft midsection, and strong thighs, posed upright with her hands clasped behind her back. Her face is intentionally anonymized by a large vertical rectangular mosaic/blur block in natural skin tones covering the entire face area, while brown hair is tied back in a low ponytail with loose side strands visible. She wears a dark green two-piece track uniform: a racerback sports crop top with white trim and side panels, plus matching brief-style athletic bottoms with white side stripes, both with small white athletic logos. Use natural daylight, sharp documentary photo realism, realistic skin texture, slight perspiration sheen, centered composition, portrait orientation, medium telephoto perspective, and a neutral candid sports-club look. Background should remain simple and uncluttered, emphasizing the single athlete and the concrete wall.
