Emily (Q-DR) started at 8:43 AM; Roger (N-DR) started at 8:41 AM. That gave Roger a 2 minutes head start on Emily. On foot, Emily ran 1:25:28 and Roger ran 1:27:24 — Emily was 1:56 faster than Roger. Emily took official place 799th (time-based 802nd) and Roger took official place 798th (time-based 848th). Roger's head start was enough to flip the official order even though Emily was faster on foot. Biggest swing: Emily gained 3:35 from Cardiac to White Gate.
