Lisa (L-DR) started at 8:39 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 29 minutes head start on Lisa because the Runner wave starts 27 minutes after the Invitational wave. On foot, Lisa ran 1:47:17 and Chris ran 1:00:42 — Chris was 46:35 faster than Lisa. Lisa took official place 1184th (time-based 1200th) 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 13:44 from Cardiac to White Gate.
