Interpretation
Stella (AAA-DR) started at 8:27 AM; Christopher (W-DR) started at 8:48 AM. That gave Stella a 21 minutes head start on Christopher. On foot, Stella ran 2:01:42 and Christopher ran 1:40:52 — Christopher was 20:50 faster than Stella. Stella took official place 1205th (time-based 1295th) and Christopher took official place 1210th (time-based 1109th).
