Interpretation
Ada (L-DR) started at 8:39 AM; Grace (N-DR) started at 8:41 AM. That gave Ada a 2 minutes head start on Grace. On foot, Ada ran 1:39:07 and Grace ran 1:37:14 — Grace was 1:53 faster than Ada. Ada took official place 1047th (time-based 1079th) and Grace took official place 1049th (time-based 1060th). Ada's head start was enough to flip the official order even though Grace was faster on foot. Biggest swing: Grace gained 1:27 from Muir Woods to Cardiac.
