Interpretation
Tracy (L-DR) started at 8:39 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 29 minutes head start on Tracy because the Runner wave starts 27 minutes after the Invitational wave. On foot, Tracy ran 2:05:03 and Chris ran 1:00:42 — Chris was 1:04:21 faster than Tracy. Tracy took official place 1315th (time-based 1310th) 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 23:56 from Muir Woods to Cardiac.
