"Create a realistic-style wide poster. On the left, depict a muscular male runner in profile, running towards to left with strong, defined muscles and a dynamic running pose, emphasizing speed and power. On the right, a similarly athletic female runner in profile, running towards to right, with toned muscles and graceful motion. Both figures should convey energy, strength, and youthful vitality. The background should be a outdoor scene, such as a park or road. Use a bright, energetic color palette with vibrant greens, blues, and oranges to enhance the sense of vitality and movement.
