Interpretation

Eric (W-DR) started at 8:48 AM; John (X-DR) started at 8:49 AM. That gave Eric a 1 minute head start on John. On foot, Eric ran 1:28:49 and John ran 1:27:57 — John was 0:52 faster than Eric. Eric took official place 1015th (time-based 879th) and John took official place 1019th (time-based 863rd). Eric's head start was enough to flip the official order even though John was faster on foot.
