Interpretation
Jay (W-DR) started at 8:48 AM; Russell (T-DR) started at 8:45 AM. That gave Russell a 3 minutes head start on Jay. On foot, Jay ran 1:10:00 and Russell ran 1:12:32 — Jay was 2:32 faster than Russell. Jay took official place 609th (time-based 322nd) and Russell took official place 605th (time-based 409th). Russell's head start was enough to flip the official order even though Jay was faster on foot. Biggest swing: Jay gained 0:38 from Cardiac to White Gate.
