Interpretation
Spencer (X-DR) started at 8:49 AM; Lloyd (AAA-INV) started at 8:00 AM. That gave Lloyd a 49 minutes head start on Spencer because the Runner wave starts 27 minutes after the Invitational wave. On foot, Spencer ran 1:39:19 and Lloyd ran 2:27:11 — Spencer was 47:52 faster than Lloyd. Spencer took official place 1198th (time-based 1083rd) and Lloyd took official place 1194th (time-based 1363rd). Lloyd's head start was enough to flip the official order even though Spencer was faster on foot. Biggest swing: Spencer gained 14:28 from Muir Woods to Cardiac.
