After Augustus' performance, there's nothing worth noting anymore from other recruits. As the agility test finished, the number of participants is reduced by half again.
"Ahem, next is the stamina test. This one is very simple: just run on the treadmill as long as you can," the examiner pointed at the machine that had been brought out, which was being switched out by the giant box.
"You can increase the speed of the treadmill to speed up the process, but you must reach the end of the destination without halting. Of course, you can't lower the speed. The stamina test commences."
Since there are many treadmills brought out, mainly because the test hall is huge, the test is actually progressing faster than previous tests.
Coincidentally, Augustus is running just beside Chloe, who's constantly glancing at him as she increases the speed of the treadmill.
