NB40-44: Irais Garcia Edges Out a Wire-to-Wire Win in San Francisco

• Irais Garcia took the NB40-44 title in 2:15:34 (10:20/mi), climbing from 8th to 6th among non-binary finishers by race's end.
• Mark Oshiro finished just 47 seconds back in 2:16:21 — a runner who also claimed 2nd in the Saturday 5K earlier in the weekend.
• Jb Rosenberg and Kim Na rounded out the middle of the field in 2:25:37 and 2:29:05, respectively, separated by nearly 3.5 minutes.
• Mike Guerrero completed the five-person field in 2:54:53 (13:20/mi), finishing 22nd among non-binary runners.

Under scattered clouds and a stiff 14 mph wind off the Bay, Irais Garcia ran a composed race from start to finish. The 44-year-old Los Angeles native held 8th among non-binary finishers early and steadily worked up to 6th by the finish line, crossing in 2:15:34 at a 10:20/mi clip — the strongest effort in the NB40-44 field. Garcia also posted the 2nd-fastest non-binary split on the 10.26M–10.5M stretch, a late-race burst that helped cement the win.

Mark Oshiro, 42, from Atlanta, ran a remarkably similar race — 10:24/mi and a 2:16:21 finish — just 47 seconds behind Garcia. Oshiro also posted the 7th-fastest non-binary split on the 9.6M–10.26M segment, showing real strength in the back half. What makes Oshiro's story particularly compelling: this half marathon came on the heels of a 2nd-place finish in the Saturday 5K, making for an impressive multi-race weekend at the San Francisco Marathon event.

Oakland's Jb Rosenberg, 41, held steady through the middle miles before fading slightly in the standings, finishing 3rd in NB40-44 in 2:25:37. Rosenberg did flash some late-race speed, recording the 11th-fastest non-binary split on the 10.5M–12M segment. San Francisco local Kim Na, 42, ran a controlled first half — posting the 11th-fastest non-binary split on the 4M–6M stretch — before slipping back to 4th in 2:29:05. Mike Guerrero, 41, of Cotati, CA, rounded out the field in 2:54:53, finishing 22nd among non-binary runners and 5th in NB40-44.
