Interpretation

Jeff (M-DR) started at 8:40 AM; Erik (P-DR) started at 8:42 AM. That gave Jeff a 2 minutes head start on Erik. On foot, Jeff ran 1:22:45 and Erik ran 1:20:46 — Erik was 1:59 faster than Jeff. Jeff took official place 679th (time-based 729th) and Erik took official place 680th (time-based 671st). Jeff's head start was enough to flip the official order even though Erik was faster on foot. Biggest swing: Erik gained 3:59 from Muir Woods to Cardiac.
