THE IMPORTANCE OF CUT-OFF TIMES IN SWIMMING EVENT

Cut-off times in swimming events serve several vital functions that enhance both the efficiency and safety of athletes.

Firstly, they ensure that all athletes can finish their races within a specified timeframe, facilitating a well-organized schedule.
Secondly, cut-off times are crucial for the safety of swimmers, especially in longer distances and Open Water Swims, as they help prevent exhaustion and potential risks in the water.
Additionally, they enable club leaders to manage the event effectively, ensuring accurate timing and results without unnecessary delays.
