The image shows a group of people swimming in a large indoor swimming pool. There are six people in the pool, all of them are in the middle of a backstroke race. The water is clear and blue, and there are red and white lane dividers on either side of the lane. The swimmers are wearing swimsuits and appear to be in the process of competing in the race. In the background, there are other swimmers and spectators watching the race from the sidelines. The pool appears to be well-maintained and well-lit.
