Interpretation
Knute (P-DR) started at 8:42 AM; Walter (AAA-DR) started at 8:27 AM. That gave Walter a 15 minutes head start on Knute. On foot, Knute ran 2:40:04 and Walter ran 2:49:57 — Knute was 9:53 faster than Walter. Knute took official place 1391st (time-based 1378th) and Walter took official place 1388th (time-based 1385th).
