NB40-44: Garcia Edges Out a 47-Second Win in San Francisco

• Irais Garcia took the NB40-44 title in 2:15:34 (10:20/mi), posting the 2nd-fastest women's split on the 10M→10.5M segment en route to the win.
• Mark Oshiro was the runner-up in 2:16:21 — just 47 seconds back — and arrived in San Francisco fresh off a 2nd-place finish in Saturday's 5K, making his weekend a genuine double podium.
• Jb Rosenberg claimed 3rd in 2:25:37, while Kim Na and Mike Guerrero rounded out the five-finisher field in 2:29:05 and 2:54:53, respectively.
• The 59°F morning with 14 mph winds off the Bay set a brisk, testing backdrop for all five competitors.

Irais Garcia, 44, from Los Angeles, controlled the NB40-44 race from start to finish with steady composure. She climbed as high as 6th among the women by the final stretch, and her sharpest moment came on the 10M→10.5M segment, where she put up the 2nd-fastest women's split in the field — a burst that underscored she wasn't just managing a lead, she was racing. Her 10:20/mi average held firm across 13.1 miles to deliver the title in 2:15:34.

Right behind her, Mark Oshiro of Atlanta made this a genuinely contested race. He steadily moved through the women's field — from 10th at the opening checkpoint all the way to 7th by the finish — and logged the 7th-fastest women's split on the 9.6M→10M stretch. He couldn't quite close the 47-second gap on Garcia, but given that he'd already raced to a 2nd-place finish in Saturday's 5K, the back-to-back podium performance across the weekend is one of the better stories in this field.

Jb Rosenberg, 41, out of Oakland, held 3rd in 2:25:37 at an 11:06/mi clip, with the 11th-fastest women's split on the 10.5M→12M segment keeping her position secure in the closing miles. Kim Na, also 42 and racing on home turf in San Francisco, finished 4th in 2:29:05, her strongest segment coming early — an 11th-fastest women's split on the 4M→6M stretch. Mike Guerrero of Cotati completed the field in 2:54:53, fading from 15th among women at the first checkpoint to 22nd by mid-race and holding there to the line.
