Interpretation
Lisa (L-DR) started at 8:39 AM; Eva (K-DR) started at 8:38 AM. That gave Eva a 1 minute head start on Lisa. On foot, Lisa ran 1:47:17 and Eva ran 1:48:06 — Lisa was 0:49 faster than Eva. Lisa took official place 1184th (time-based 1200th) and Eva took official place 1180th (time-based 1211th). Eva's head start was enough to flip the official order even though Lisa was faster on foot.
