Interpretation
Megan (L-INV) started at 8:12 AM; Henry (X-INV) started at 8:22 AM. That gave Megan a 10 minutes head start on Henry. On foot, Megan ran 1:16:53 and Henry ran 1:06:55 — Henry was 9:58 faster than Megan. Megan took official place 247th (time-based 549th) and Henry took official place 252nd (time-based 227th).
