Felix (X-INV) started at 8:22 AM; Anna (P-INV) started at 8:15 AM. That gave Anna a 7 minutes head start on Felix. On foot, Felix ran 1:10:13 and Anna ran 1:17:07 — Felix was 6:54 faster than Anna. Felix took official place 361st (time-based 333rd) and Anna took official place 358th (time-based 558th). Anna's head start was enough to flip the official order even though Felix was faster on foot.
