Athlete B
OfficialMark B Miller
#1343 · 2:51:19 · M74 · Group AAA · INV
Wave start 8:00 AM (AAA-INV)
Interpretation
Tien (Y-DR) started at 8:50 AM; Mark (AAA-INV) started at 8:00 AM. That gave Mark a 50 minutes head start on Tien because the Runner wave starts 27 minutes after the Invitational wave. On foot, Tien ran 2:02:54 and Mark ran 2:51:19 — Tien was 48:25 faster than Mark. Tien took official place 1348th (time-based 1303rd) and Mark took official place 1343rd (time-based 1386th). Mark's head start was enough to flip the official order even though Tien was faster on foot. Biggest swing: Tien gained 15:37 from Muir Woods to Cardiac.
