SF Marathon 10K: Kim Na Owns NB40-44

• Sole finisher and winner: Kim Na, age 40, crossed in 1:00:37 at a 9:45/mi average pace.
• Consistent women's field position: Held 5th among women from the 4.62-mile mark all the way to the finish line.
• Strong closing stretch: Recorded the 5th-fastest women's split on the 4.62M-to-Finish segment.

Kim Na stepped to the start line in San Francisco's cool, overcast morning — 57°F with barely a breath of wind — as the only NB40-44 competitor in the field, and she made every step count. Her 1:00:37 finish at 9:45/mi wasn't just a win by default; it was a genuinely solid effort in a real women's field, and the numbers back that up.

What stands out most is how Na raced against the broader women's field around her. She held 5th among women from the 4.62-mile checkpoint all the way to the tape — a position she neither surrendered nor improved upon, a sign of a steady, controlled effort with no late drama. And on that final stretch to the finish, she posted the 5th-fastest women's split in the field, meaning she was moving with purpose when it mattered most.

A solo NB40-44 podium is still a podium — and Na claimed it with a performance that held its own well beyond the boundaries of her own group.
