Women's Ultramarathon: Dueck Dominates 52.4 Miles Through the Fog

• Vanessa Dueck wins in 7:41:28 (8:48/mi), the fastest women's split on the first marathon leg sealing a wire-to-wire victory.
• Mimi Lam's second-half surge — she climbed from 6th to 4th with the 2nd-fastest women's split on the first marathon leg, finishing 8:26:55 at age 52.
• Lam and Shikha Pahwa finished just 8 seconds apart (8:26:55 vs. 8:27:03), the closest gap in the women's field, though Pahwa faded from 4th to 5th on the second leg while Lam charged forward.
• Justine Okeefe returns — she finished 8th in 10:35:05, back on the course after her 3rd-place finish here in 2023 (10:07:56).

Vanessa Dueck held the lead from start to finish across all 52.4 miles of this one-of-a-kind urban ultra — a double loop of the full San Francisco Marathon course, crossing the Golden Gate Bridge and winding through Golden Gate Park twice. Running at 8:48/mi through cool, humid morning air, she posted the fastest women's split on the first marathon leg and never looked back, finishing in 7:41:28 — more than 23 minutes clear of second place.

Behind her, the real drama unfolded in the middle of the pack. Ann Galvan (8:04:41) moved from 3rd to 2nd on the back half with the 3rd-fastest women's first-leg split, while Lisa Hughey (8:06:39) slipped from 2nd to 3rd despite posting the 5th-fastest first-leg split among women — a two-minute gap separating them at the line. Mimi Lam's run deserves its own spotlight: climbing from 6th place to 4th while running the 2nd-fastest first-leg split in the women's field, the 52-year-old from Vacaville finished in 8:26:55, just eight seconds ahead of Shikha Pahwa (8:27:03), who had faded from 4th to 5th on the return loop.

Lauren Korsnick, at 22 the youngest finisher in the women's field, crossed 6th in 8:43:34 — a solid result in a race that humbles most first-timers. Further back, Justine Okeefe made a determined return to this course, finishing 8th in 10:35:05 after her podium appearance here in 2023. All 14 women who started found the finish line, completing a demanding day of running through one of America's most iconic cities.
