Sports portrait of a Japanese female runner in a starting pose on a stadium track, wearing a dark navy uniform with bib number 15-2

Prompt

Create an ultra-realistic vertical sports photograph of an adult Japanese female track-and-field sprinter on an outdoor stadium running track, framed from mid-thigh to above the head in a close portrait crop. She is leaning forward in a pre-race crouch with both arms extended downward, shoulders and upper body prominent, wearing a dark navy or black two-piece racing uniform with a sleeveless crop top and matching racing briefs, with thin red-and-white trim at the hips. Add a white competition bib pinned across her chest with red Japanese sponsor text and the visible race number 15-2, plus a small white Mizuno-style logo on the upper chest. Her dark brown hair is long and tied back in a low ponytail with loose strands catching the sunlight. Place a plain rectangular privacy blur or solid skin-toned block over the face, centered from forehead to chin, while keeping the ears, hairline, neck, shoulders, and body realistically visible. The setting is a sunny athletics stadium with a red running track, white lane markings, and a distant out-of-focus crowd and stands rendered as soft blue-gray bokeh. Use natural daylight, strong backlighting on the hair and shoulders, shallow depth of field, realistic skin texture, authentic sports-photo lens compression, high detail, candid professional photography style, no illustration, no anime, no glamour posing, no text other than the bib.
