Interpretation
Maria (M-DR) started at 8:40 AM; Ned (T-DR) started at 8:45 AM. That gave Maria a 5 minutes head start on Ned. On foot, Maria ran 1:41:41 and Ned ran 1:36:45 — Ned was 4:56 faster than Maria. Maria took official place 1105th (time-based 1119th) and Ned took official place 1107th (time-based 1051st).
