Interpretation

Gretchen (Q-INV) started at 8:16 AM; Geoff (M-INV) started at 8:13 AM. That gave Geoff a 3 minutes head start on Gretchen. On foot, Gretchen ran 1:18:35 and Geoff ran 1:21:24 — Gretchen was 2:49 faster than Geoff. Gretchen took official place 430th (time-based 595th) and Geoff took official place 427th (time-based 690th).
