In the 401 Skills, how far must children swim using the free stroke with roll breathing?

The correct distance for children to swim using the free stroke with roll breathing in the 401 Skills is 15 yards. This requirement is designed to ensure that children can effectively demonstrate the technique and endurance associated with the free stroke, which is essential for building confidence in their swimming abilities. The focus on a shorter distance like 15 yards allows young swimmers to concentrate on their form and technique without being overwhelmed by longer distances, fostering skill mastery at an appropriate developmental level. Understanding this aspect is crucial for instructors as they assess a child's readiness and progress in swimming skills.
