San Francisco Half Marathon 2025: Autumn Fox Runs Down the Win in F30-34

• Autumn Fox took the F30-34 title in 1:38:31 (7:31/mi), posting the 14th-fastest women's split on the second half as she climbed from 19th to 11th among women.
• Minfeng Lu finished 2nd in 1:38:47 — just 16 seconds back — having run the 12th-fastest women's split on the 1.81M–5.34M segment to build her early position.
• Phoebe Miller (3rd, 1:40:37) and Katie Maklebust (4th, 1:41:00) both delivered top-20 women's splits on the 6.15M–10.54M segment — Miller's 18th-fastest and Maklebust's 17th-fastest — separated by just 23 seconds at the finish.
• The top 4 all broke 1:42; the next finisher, Ganna Rybalchenko in 5th at 1:44:59, was nearly 4 minutes further back.

Autumn Fox didn't lead early. Sitting 19th among women through the opening miles, she was patient while Minfeng Lu — already 8th among women by the 1.81M mark — built a strong cushion up front. Fox began moving through the field steadily, and by the time the second half of the course arrived, she was ready to press. Her 14th-fastest women's split on the back half was the decisive move, carrying her from 14th to 11th among women and, more importantly, clear of Lu for the F30-34 win.

Lu, for her part, was no pushover. She ran an excellent early segment — 12th-fastest among women from 1.81M to 5.34M — and held her position well into the race. Her 1:38:47 finish was a genuinely strong effort; Fox simply ran the second half faster, and that gap of 16 seconds tells the story of a race decided late.

Behind them, Phoebe Miller and Katie Maklebust waged a compelling battle of their own. Both women were mid-pack among women early and both surged through the 6.15M–10.54M stretch with nearly identical aggression — Maklebust's 17th-fastest women's split on that segment edging Miller's 18th — yet Miller held 3rd by 23 seconds at the line. Ganna Rybalchenko (5th, 1:44:59) and Victoria Haas (6th, 1:45:06) rounded out the top six within seven seconds of each other, while the rest of a 691-finisher field stretched out across the San Francisco streets behind them.
