The image shows a large indoor swimming pool with multiple lanes. There are three swimmers in the pool, all wearing swimsuits and diving into the water. The swimmers are in the middle of a backstroke race, with their arms and legs stretched out in front of them. The pool is filled with blue water and there are red and white lane dividers on the sides. On the left side of the image, there are a few spectators watching the swimmers. The ceiling of the pool is high and has large windows, allowing natural light to enter the space.
