Interpretation
Thomas (P-DR) started at 8:42 AM; Jean (N-DR) started at 8:41 AM. That gave Jean a 1 minute head start on Thomas. On foot, Thomas ran 1:51:12 and Jean ran 1:52:04 — Thomas was 0:52 faster than Jean. Thomas took official place 1249th (time-based 1237th) and Jean took official place 1247th (time-based 1247th). Jean's head start was enough to flip the official order even though Thomas was faster on foot. Biggest swing: Thomas gained 1:35 from Windy Gap to Muir Woods.
