Interpretation
Laura (J-DR) started at 8:37 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 27 minutes head start on Laura because the Runner wave starts 27 minutes after the Invitational wave. On foot, Laura ran 2:08:38 and Chris ran 1:00:42 — Chris was 1:07:56 faster than Laura. Laura took official place 1319th (time-based 1327th) 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 20:01 from Muir Woods to Cardiac.
