Interpretation
Mary (L-DR) started at 8:39 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 29 minutes head start on Mary because the Runner wave starts 27 minutes after the Invitational wave. On foot, Mary ran 1:32:11 and Chris ran 1:00:42 — Chris was 31:29 faster than Mary. Mary took official place 871st (time-based 948th) 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 12:09 from Muir Woods to Cardiac.
