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