Interpretation
Russell (T-DR) started at 8:45 AM; John (N-DR) started at 8:41 AM. That gave John a 4 minutes head start on Russell. On foot, Russell ran 1:12:32 and John ran 1:16:19 — Russell was 3:47 faster than John. Russell took official place 605th (time-based 409th) and John took official place 601st (time-based 530th). John's head start was enough to flip the official order even though Russell was faster on foot. Biggest swing: Russell gained 3:38 from Muir Woods to Cardiac.
