Interpretation
Stephen (X-INV) started at 8:22 AM; Kevin (U-INV) started at 8:19 AM. That gave Kevin a 3 minutes head start on Stephen. On foot, Stephen ran 1:01:36 and Kevin ran 1:04:27 — Stephen was 2:51 faster than Kevin. Stephen took official place 117th (time-based 97th) and Kevin took official place 113th (time-based 165th).
