Athlete B

Official

Chris Lundy

Wave start 8:10 AM (J-INV)

Interpretation

Adam (SCR-DR) started at 8:52 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 42 minutes head start on Adam because the Runner wave starts 27 minutes after the Invitational wave. On foot, Adam ran 1:11:20 and Chris ran 1:00:42 — Chris was 10:38 faster than Adam. Adam took official place 689th (time-based 360th) 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 4:54 from Muir Woods to Cardiac.
