Interpretation
Luke (SCR-DR) started at 8:52 AM; Chris (Q-DR) started at 8:43 AM. That gave Chris a 9 minutes head start on Luke. On foot, Luke ran 1:17:45 and Chris ran 1:26:38 — Luke was 8:53 faster than Chris. Luke took official place 824th (time-based 574th) and Chris took official place 820th (time-based 823rd). Chris's head start was enough to flip the official order even though Luke was faster on foot. Biggest swing: Luke gained 2:35 from Muir Woods to Cardiac.
