Interpretation
Craig (Z-INV) started at 8:24 AM; Steven (W-INV) started at 8:21 AM. That gave Steven a 3 minutes head start on Craig. On foot, Craig ran 1:08:28 and Steven ran 1:11:21 — Craig was 2:53 faster than Steven. Craig took official place 370th (time-based 271st) and Steven took official place 365th (time-based 364th). Steven's head start was enough to flip the official order even though Craig was faster on foot. Biggest swing: Craig gained 1:01 from Muir Woods to Cardiac.
