Interpretation
Henry (X-INV) started at 8:22 AM; Sarah (Q-INV) started at 8:16 AM. That gave Sarah a 6 minutes head start on Henry. On foot, Henry ran 1:06:55 and Sarah ran 1:12:55 — Henry was 6:00 faster than Sarah. Henry took official place 252nd (time-based 227th) and Sarah took official place 251st (time-based 423rd).
