Interpretation
Richie (Z-DR) started at 8:51 AM; Anne (P-DR) started at 8:42 AM. That gave Anne a 9 minutes head start on Richie. On foot, Richie ran 1:19:06 and Anne ran 1:28:05 — Richie was 8:59 faster than Anne. Richie took official place 838th (time-based 621st) and Anne took official place 837th (time-based 868th). Anne's head start was enough to flip the official order even though Richie was faster on foot. Biggest swing: Richie gained 3:08 from Cardiac to White Gate.
