The image shows a large indoor swimming pool with multiple lanes. There are three swimmers in the pool, all wearing swimsuits and goggles. The swimmers are in the middle of a backstroke race, with their arms and legs stretched out in front of them. The water is a bright blue color and there are white and blue lane dividers on the sides of the pool. On the right side of the image, there is a crowd of people standing on the edge of the lane, watching the swimmers. In the background, there are yellow caution signs hanging from the ceiling and a large window on the left side. The pool appears to be well-lit with natural light coming in from the windows.
