Interpretation
Christopher (W-INV) started at 8:21 AM; Gordon (Y-DR) started at 8:50 AM. That gave Christopher a 29 minutes head start on Gordon because the Runner wave starts 27 minutes after the Invitational wave. On foot, Christopher ran 1:30:05 and Gordon ran 1:01:06 — Gordon was 28:59 faster than Christopher. Christopher took official place 554th (time-based 914th) and Gordon took official place 555th (time-based 86th). Christopher's head start was enough to flip the official order even though Gordon was faster on foot. Biggest swing: Gordon gained 12:04 from Muir Woods to Cardiac.
