Interpretation

Susan (J-DR) started at 8:37 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 27 minutes head start on Susan because the Runner wave starts 27 minutes after the Invitational wave. On foot, Susan ran 1:49:55 and Chris ran 1:00:42 — Chris was 49:13 faster than Susan. Susan took official place 1190th (time-based 1226th) and Chris took official place 1st (time-based 71st). Chris was faster on foot and finished ahead on the official clock too. Biggest swing: Chris gained 20:27 from Muir Woods to Cardiac.
