Interpretation
Michael (Y-INV) started at 8:23 AM; Doug (B-INV) started at 8:03 AM. That gave Doug a 20 minutes head start on Michael. On foot, Michael ran 59:04 and Doug ran 1:19:03 — Michael was 19:59 faster than Doug. Michael took official place 87th (time-based 55th) and Doug took official place 86th (time-based 618th). Doug's head start was enough to flip the official order even though Michael was faster on foot. Biggest swing: Michael gained 7:31 from Muir Woods to Cardiac.
