Staff members, including the training officers, were positioned in the front, middle and back of the line of runners to monitor the cadets. Following the runners was a large Ford E350 XL Super Duty van with air conditioning and water, which could seat 12 employees. As Employee #1 ran approximately 2.25 miles, he told his training officer that he was not feeling well. The training officer instructed him to fall out and stop running.
