The prerequisite for this class is a 50/50 swim. This is when you swim 50 yards then tread for 2 minutes without using your hands, then swim another 50 yards. Then the participant must complete the timed test. They will start in the water and swim 20 yards to retrieve a 10-pound brick from the bottom of the pool and swim on their back to the starting point. The participant must then exit the water. IF you want to practice these please reach out to Arissa at afriesen@blackhawkymca.org.
