Interpretation
John (B-DR) started at 8:30 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 20 minutes head start on John because the Runner wave starts 27 minutes after the Invitational wave. On foot, John ran 1:23:14 and Chris ran 1:00:42 — Chris was 22:32 faster than John. John took official place 570th (time-based 747th) 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 8:02 from Cardiac to White Gate.
