Interpretation
Anna (Q-INV) started at 8:16 AM; Nolan (SCR-INV) started at 8:25 AM. That gave Anna a 9 minutes head start on Nolan. On foot, Anna ran 58:02 and Nolan ran 49:59 — Nolan was 8:03 faster than Anna. Anna took official place 7th (time-based 39th) and Nolan took official place 10th (time-based 3rd). Anna's head start was enough to flip the official order even though Nolan was faster on foot.
