Interpretation
Tien (Y-DR) started at 8:50 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 40 minutes head start on Tien because the Runner wave starts 27 minutes after the Invitational wave. On foot, Tien ran 2:02:54 and Chris ran 1:00:42 — Chris was 1:02:12 faster than Tien. Tien took official place 1348th (time-based 1303rd) 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 24:35 from Muir Woods to Cardiac.
