Gidon (M-INV) started at 8:13 AM; Liam (Z-INV) started at 8:24 AM. That gave Gidon a 11 minutes head start on Liam. On foot, Gidon ran 1:22:37 and Liam ran 1:11:44 — Liam was 10:53 faster than Gidon. Gidon took official place 456th (time-based 724th) and Liam took official place 461st (time-based 381st). Gidon's head start was enough to flip the official order even though Liam was faster on foot.
