Interpretation
Gregg (B-DR) started at 8:30 AM; Julia (Q-DR) started at 8:43 AM. That gave Gregg a 13 minutes head start on Julia. On foot, Gregg ran 2:19:55 and Julia ran 2:06:56 — Julia was 12:59 faster than Gregg. Gregg took official place 1336th (time-based 1351st) and Julia took official place 1337th (time-based 1319th). Gregg's head start was enough to flip the official order even though Julia was faster on foot. Biggest swing: Julia gained 7:43 from Muir Woods to Cardiac.
