Interpretation
Eva (K-DR) started at 8:38 AM; Lisa (L-DR) started at 8:39 AM. That gave Eva a 1 minute head start on Lisa. On foot, Eva ran 1:48:06 and Lisa ran 1:47:17 — Lisa was 0:49 faster than Eva. Eva took official place 1180th (time-based 1211th) and Lisa took official place 1184th (time-based 1200th). Eva's head start was enough to flip the official order even though Lisa was faster on foot. Biggest swing: Lisa gained 5:16 from Muir Woods to Cardiac.
