Interpretation
Jaclyn (M-INV) started at 8:13 AM; Christopher (P-INV) started at 8:15 AM. That gave Jaclyn a 2 minutes head start on Christopher. On foot, Jaclyn ran 1:18:24 and Christopher ran 1:16:30 — Christopher was 1:54 faster than Jaclyn. Jaclyn took official place 338th (time-based 590th) and Christopher took official place 340th (time-based 539th).
