Interpretation
Sarah (G-DR) started at 8:35 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 25 minutes head start on Sarah because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sarah ran 1:38:14 and Chris ran 1:00:42 — Chris was 37:32 faster than Sarah. Sarah took official place 914th (time-based 1070th) 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 14:29 from Muir Woods to Cardiac.
