Interpretation
William (P-DR) started at 8:42 AM; Karen (L-DR) started at 8:39 AM. That gave Karen a 3 minutes head start on William. On foot, William ran 1:51:59 and Karen ran 1:54:49 — William was 2:50 faster than Karen. William took official place 1258th (time-based 1246th) and Karen took official place 1255th (time-based 1258th). Karen's head start was enough to flip the official order even though William was faster on foot. Biggest swing: William gained 2:00 from Cardiac to White Gate.
