Generate a 4K, photorealistic image of a female model wearing activewear leggings and a sports bra, captured in a candid moment of running or jogging through an urban environment. The artistic style will be contemporary realism, and the image will have a high-energy feel with a fast shutter speed (1/2000s) to freeze motion. Bright, mid-day natural lighting will create dynamic shadows on the model’s outfit, highlighting the material’s breathability and stretch. The background will be blurred slightly to enhance the sense of speed, with urban elements like skyscrapers or streets faintly visible. Focus on the model's movement, especially the flowing fabric of the leggings. Apply subtle HDR to sharpen details and a light motion blur to emphasize action.
