Interpretation
Shannon (Q-INV) started at 8:16 AM; Greg (H-INV) started at 8:09 AM. That gave Greg a 7 minutes head start on Shannon. On foot, Shannon ran 1:10:43 and Greg ran 1:17:34 — Shannon was 6:51 faster than Greg. Shannon took official place 195th (time-based 346th) and Greg took official place 192nd (time-based 572nd). Greg's head start was enough to flip the official order even though Shannon was faster on foot. Biggest swing: Shannon gained 3:06 from Muir Woods to Cardiac.
