Thor (Q-INV) started at 8:16 AM; Chris (V-INV) started at 8:20 AM. That gave Thor a 4 minutes head start on Chris. On foot, Thor ran 1:07:56 and Chris ran 1:03:58 — Chris was 3:58 faster than Thor. Thor took official place 124th (time-based 259th) and Chris took official place 128th (time-based 152nd). Thor's head start was enough to flip the official order even though Chris was faster on foot.
