Interpretation
Elton (V-INV) started at 8:20 AM; Gretchen (Q-INV) started at 8:16 AM. That gave Gretchen a 4 minutes head start on Elton. On foot, Elton ran 1:14:45 and Gretchen ran 1:18:35 — Elton was 3:50 faster than Gretchen. Elton took official place 434th (time-based 469th) and Gretchen took official place 430th (time-based 595th).
