Interpretation
Eric (T-DR) started at 8:45 AM; Margaret (G-DR) started at 8:35 AM. That gave Margaret a 10 minutes head start on Eric. On foot, Eric ran 1:56:37 and Margaret ran 2:06:33 — Eric was 9:56 faster than Margaret. Eric took official place 1304th (time-based 1269th) and Margaret took official place 1301st (time-based 1316th). Margaret's head start was enough to flip the official order even though Eric was faster on foot. Biggest swing: Eric gained 8:07 from Cardiac to White Gate.
