Interpretation
Lisa (L-DR) started at 8:39 AM; Emma (K-DR) started at 8:38 AM. That gave Emma a 1 minute head start on Lisa. On foot, Lisa ran 1:47:17 and Emma ran 1:48:17 — Lisa was 1:00 faster than Emma. Lisa took official place 1184th (time-based 1200th) and Emma took official place 1183rd (time-based 1213th). Emma's head start was enough to flip the official order even though Lisa was faster on foot. Biggest swing: Lisa gained 5:10 from Muir Woods to Cardiac.
