On foot, Laura ran 2:08:38 and Rachael ran 2:03:53 — Rachael was 4:45 faster than Laura. Laura took official place 1319th (time-based 1327th) and Rachael took official place 1321st (time-based 1305th). Laura's head start was enough to flip the official order even though Rachael was faster on foot. Biggest swing: Rachael gained 3:39 from Cardiac to White Gate.
