Interpretation

Sam (W-DR) started at 8:48 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 38 minutes head start on Sam because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sam ran 1:21:46 and Chris ran 1:00:42 — Chris was 21:04 faster than Sam. Sam took official place 827th (time-based 701st) 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 10:17 from Muir Woods to Cardiac.
