Jeffrey (Y-INV) started at 8:23 AM; Brian (V-INV) started at 8:20 AM. That gave Brian a 3 minutes head start on Jeffrey. On foot, Jeffrey ran 1:07:52 and Brian ran 1:10:44 — Jeffrey was 2:52 faster than Brian. Jeffrey took official place 310th (time-based 258th) and Brian took official place 306th (time-based 348th).
