Interpretation
Sarah (Q-INV) started at 8:16 AM; Henry (X-INV) started at 8:22 AM. That gave Sarah a 6 minutes head start on Henry. On foot, Sarah ran 1:12:55 and Henry ran 1:06:55 — Henry was 6:00 faster than Sarah. Sarah took official place 251st (time-based 423rd) and Henry took official place 252nd (time-based 227th). Sarah's head start was enough to flip the official order even though Henry was faster on foot. Biggest swing: Henry gained 2:50 from Muir Woods to Cardiac.
