Interpretation
Lisa (L-DR) started at 8:39 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 15 minutes head start on Lisa because the Runner wave starts 27 minutes after the Invitational wave. On foot, Lisa ran 1:47:17 and Edward ran 48:29 — Edward was 58:48 faster than Lisa. Lisa took official place 1184th (time-based 1200th) and Edward took official place 2nd (time-based 1st). Edward was faster on foot and finished ahead on the official clock too. Biggest swing: Edward gained 17:51 from Muir Woods to Cardiac.
