Interpretation
Sarah (G-DR) started at 8:35 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 11 minutes head start on Sarah because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sarah ran 1:38:14 and Edward ran 48:29 — Edward was 49:45 faster than Sarah. Sarah took official place 914th (time-based 1070th) 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 18:47 from Muir Woods to Cardiac.
