San Francisco Marathon 10K — M50-54: Soto Leads a Bay Area Sweep

• Eduardo Soto, 52, of South San Francisco, won the M50-54 race in 40:54 (6:35/mi), the only finisher under 41 minutes.
• Zach Murphy took 2nd in 41:24 — just 30 seconds back — but gave up ground to Soto on the final stretch, running the 4.62M→Finish segment slower as Soto pulled clear.
• Michael Kuo, 54, rounded out the podium in 43:00, a full 1:36 behind Murphy and the only other sub-44 finisher in a field of 81.
• Jason Lam and John Boscardin staged a tight battle for 5th and 6th, finishing just 5 seconds apart — 49:22 to 49:27.

Eduardo Soto owned this race from start to finish. Running a 6:35/mi average through San Francisco's cool, humid Sunday morning air, the 52-year-old from South San Francisco crossed in 40:54 — a full 30 seconds clear of the field. What's more, Soto actually strengthened his position late: he moved from 34th to 33rd in the broader men's field on that closing 4.62-mile stretch, posting the 37th-fastest split on that segment among men. That's not coasting to the tape — that's finishing with authority.

Zach Murphy came in with genuine podium credentials, running a 6:40/mi pace to claim 2nd in 41:24. But the final segment told the real story: Murphy slipped from 33rd to 38th in the men's field over those closing miles, while Soto was moving the other direction. Murphy still held off the rest of the M50-54 field comfortably — Michael Kuo's 3rd-place 43:00 left a 1:36 gap — but the win was Soto's to take, and he took it decisively.

Kuo, at 54, was the oldest man on the podium and delivered the third sub-43 performance of the race at 6:55/mi. Behind him, Peter Fichtel (4th, 46:32) ran a solid 7:29/mi pace but the gap back to the top three was substantial. The race's most entertaining late battle came between Jason Lam and John Boscardin — 5th and 6th — who finished within five seconds of each other at 49:22 and 49:27 respectively, both averaging 7:57/mi. From there, 20 named finishers spread across the remaining spots, with Yasuhiro Tanaka rounding out the top 20 in 56:13 — part of a deep 81-man field that stretched across the Bay Area.
