World Athletics Championships

Create a stunning image of a gold medal for the World Athletics Championships, featuring a circular design with a diameter of 70mm, crafted from polished brass with intricate details. The medal's surface showcases an embossed representation of a sprinter in motion, surrounded by laurel leaves, symbolizing victory. A vibrant blue and gold ribbon, 1.5 inches wide, is attached, adorned with subtle patterns of running tracks. The engraving on the reverse side includes the championship year and the athlete's name in elegant script. The color scheme is a rich gold with deep blue accents, set against a softly blurred background of a stadium filled with cheering fans. The lighting should highlight the medal's reflective surfaces, creating a warm glow, while the perspective captures the medal slightly tilted, emphasizing its depth and craftsmanship, with a focus on the details of the ribbon and engravings.
