Interpretation
Linda (K-INV) started at 8:11 AM; Tom (AA-INV) started at 8:01 AM. That gave Tom a 10 minutes head start on Linda. On foot, Linda ran 1:17:31 and Tom ran 1:27:22 — Linda was 9:51 faster than Tom. Linda took official place 234th (time-based 570th) and Tom took official place 231st (time-based 846th). Tom's head start was enough to flip the official order even though Linda was faster on foot.
