Which of the following is NOT a requirement for the 15,000m bike event?

The reason that setting the resistance level to maximum is not a requirement for the 15,000m bike event is that the resistance level should be set to an appropriate level that allows the soldier to maintain a steady pace without overexerting themselves. The objective of this event is to measure endurance and cardiovascular fitness, rather than to impose maximum resistance, which could lead to fatigue and diminish performance.

Other requirements, such as ensuring the bike is validated and functioning (this helps ensure safety and accuracy in the test), allowing a short rest period but limiting it to 30 seconds (to maintain the flow of the event while accommodating necessary breaks), and having the NCOIC manage the timing of the events (ensuring that the overall testing schedule runs smoothly) are all important for maintaining the integrity and organization of the test. Setting the resistance to maximum does not align with these goals as it could compromise the test's effectiveness and the soldier’s ability to complete the event.
