Interpretation

Tom (W-DR) started at 8:48 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 38 minutes head start on Tom because the Runner wave starts 27 minutes after the Invitational wave. On foot, Tom ran 1:24:47 and Chris ran 1:00:42 — Chris was 24:05 faster than Tom. Tom took official place 907th (time-based 786th) 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 10:26 from Muir Woods to Cardiac.
