Swimming with the instuctors

On the last day of swimming with the instructors, they tested us to see where we were at. Through swimming we were doing some amazing practice with the instructors. Then it came to the end where we had to do  a challenge who had to go the longest without touching the ground. When I went in the pool it was  cold, cool and chilly and then I had to duck under the water then we starting the challenge I had 25 meters going down and back it was cool and it was the best time of my life.
