SF Marathon 10K: Zee Spencer Owns the NB35-39 Women's Field

• Zee Spencer, 36, Oakland — took the NB35-39 win in 1:03:52 (10:17/mi avg)
• 9th-fastest women's split on the 4.62M-to-Finish stretch across the entire women's field
• Held 7th place among women from the 4.62-mile mark all the way to the line

Zee Spencer showed up, ran her race, and left with the NB35-39 title — the only finisher in the category on a cool, humid Sunday morning in San Francisco. With overcast skies and barely a breath of wind at 57°F, conditions were about as cooperative as the city ever offers, and Spencer made the most of them.

What stands out beyond the win itself is how Spencer finished. On the closing 4.62-mile-to-finish segment, she posted the 9th-fastest women's split in the field — a stretch where she held steady at 7th among all women. That's not a runner coasting to a solo victory; that's someone pressing through the final miles with genuine purpose.

Her finishing time of 1:03:52 at a 10:17/mi average tells the full story of a consistent, committed effort over 6.2 miles of San Francisco's iconic — and unforgiving — streets. With no one else in the NB35-39 field to measure against, Spencer's benchmark stands as the mark to beat when this race returns in 2026.
