Athlete B

#1348 · 2:02:54 · M36 · Group Y · DR
Wave start 8:50 AM (Y-DR)
Interpretation
Mark (AAA-INV) started at 8:00 AM; Tien (Y-DR) started at 8:50 AM. That gave Mark a 50 minutes head start on Tien because the Runner wave starts 27 minutes after the Invitational wave. On foot, Mark ran 2:51:19 and Tien ran 2:02:54 — Tien was 48:25 faster than Mark. Mark took official place 1343rd (time-based 1386th) and Tien took official place 1348th (time-based 1303rd). 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.
