The 2.4km run in the IPPT (Individual Physical Proficiency Test) is a key endurance component that measures cardiovascular fitness and stamina. Participants must complete a 2.4km distance as quickly as possible, with faster times earning higher scores. Performance is graded based on age and gender, with points contributing to the overall IPPT score. Maintaining a steady pace, improving aerobic capacity, and practicing interval running can help achieve a better score.
