Interpretation
Kieran (Z-INV) started at 8:24 AM; Jan (V-INV) started at 8:20 AM. That gave Jan a 4 minutes head start on Kieran. On foot, Kieran ran 1:06:31 and Jan ran 1:10:26 — Kieran was 3:55 faster than Jan. Kieran took official place 301st (time-based 219th) and Jan took official place 298th (time-based 339th). Jan's head start was enough to flip the official order even though Kieran was faster on foot.
