According to the benchmarks, how long should a swimmer tread water for the Green Stroke School Safety Benchmark?

The appropriate duration for treading water at the Green Stroke School Safety Benchmark is 2 minutes. This benchmark is designed to ensure that swimmers develop sufficient endurance and core strength, which are critical for maintaining buoyancy and stability in the water. Treading water for this duration also serves as an important safety skill, enabling swimmers to stay afloat while waiting for assistance or assessing their surroundings.

The 2-minute requirement reflects an adequate challenge for swimmers in this skill level, allowing them to build confidence and competence in their treading water abilities. By successfully achieving this benchmark, swimmers are demonstrating their capacity to remain calm and effective in a potentially stressful situation, which is a crucial aspect of water safety.
