Interpretation
Sam (W-DR) started at 8:48 AM; Greg (K-DR) started at 8:38 AM. That gave Greg a 10 minutes head start on Sam. On foot, Sam ran 1:21:46 and Greg ran 1:31:46 — Sam was 10:00 faster than Greg. Sam took official place 827th (time-based 701st) and Greg took official place 826th (time-based 939th). Greg's head start was enough to flip the official order even though Sam was faster on foot. Biggest swing: Sam gained 2:59 from Cardiac to White Gate.
