Interpretation
Sean (Z-INV) started at 8:24 AM; Alan (L-INV) started at 8:12 AM. That gave Alan a 12 minutes head start on Sean. On foot, Sean ran 54:23 and Alan ran 1:05:26 — Sean was 11:03 faster than Alan. Sean took official place 37th (time-based 14th) and Alan took official place 32nd (time-based 192nd). Alan's head start was enough to flip the official order even though Sean was faster on foot.
