SF Marathon 5K — NB30-34: Chung Claims the Division Win

• Jc Chung took 1st in the NB30-34 field with a time of 31:23 (10:06/mi).
• Jasper Lamadora finished 2nd in 33:50 (10:53/mi) — 2:27 back of Chung.
• Onurkan Karabulut rounded out the three-man field in 3rd at 36:23 (11:43/mi), finishing 2:33 behind Lamadora.

Three men lined up for the NB30-34 race on a cool, overcast Sunday morning in San Francisco — 55°F with a stiff marine layer and 89% humidity making for thick, damp conditions along the course. Jc Chung of Belmont led the way from start to finish, crossing in 31:23 at a 10:06/mi clip to take the win by a clear margin.

Jasper Lamadora of Pacifica gave chase, completing the 5K in 33:50 — a 10:53/mi pace that kept him solidly in 2nd but couldn't close the 2:27 gap to Chung. San Francisco local Onurkan Karabulut brought it home in 3rd at 36:23, running an 11:43/mi average and finishing 2:33 behind Lamadora. The gaps between each finisher were remarkably consistent — Chung won the NB30-34 field with room to spare, while Lamadora and Karabulut each ran their own race to the line.
