Interpretation
Maria (M-DR) started at 8:40 AM; George (V-DR) started at 8:47 AM. That gave Maria a 7 minutes head start on George. On foot, Maria ran 1:41:41 and George ran 1:34:46 — George was 6:55 faster than Maria. Maria took official place 1105th (time-based 1119th) and George took official place 1109th (time-based 1005th). Maria's head start was enough to flip the official order even though George was faster on foot. Biggest swing: George gained 4:15 from Muir Woods to Cardiac.
