Avery (N-INV) started at 8:14 AM; Rob (Y-INV) started at 8:23 AM. That gave Avery a 9 minutes head start on Rob. On foot, Avery ran 1:10:41 and Rob ran 1:01:50 — Rob was 8:51 faster than Avery. Avery took official place 142nd (time-based 345th) and Rob took official place 147th (time-based 104th). Avery's head start was enough to flip the official order even though Rob was faster on foot.
