Masters Men 5K: Isanuk Wins the Bay City Battle at 6:36 Pace

• Matthew Isanuk took the Masters Men title in 20:29 (6:36/mi), beating runner-up Thomas Teisseyre by 20 seconds.
• Juan Rangel, age 57, cracked the top five in 22:59 — outrunning competitors a decade-plus younger.
• Douglas Vetter, age 67, ran 26:32 to claim 14th in a 235-man field — one of the oldest finishers in the top 15.
• Lawrence Chiu doubled up across the weekend, finishing 4th here in 22:21 after placing 10th in the men's 5K on Saturday — a genuine two-race feat worth noting.

San Francisco's waterfront delivered a brisk Sunday morning — 56°F, 14 mph winds, and 95% humidity — and the Masters Men answered with some sharp racing. Matthew Isanuk, 40, of San Francisco, set the tone from the start, clocking a 6:36/mi average to finish in 20:29 and claim the title. Thomas Teisseyre of Montara ran a solid 6:42/mi to cross in 20:49, but Isanuk's 20-second cushion was never seriously threatened. Sam Slee rounded out the podium in 21:36 (6:57/mi), a further 47 seconds back.

The race's most compelling subplot belonged to Juan Rangel. At 57, he ran 22:59 at a 7:24/mi clip to finish 5th — ahead of several men 10 to 15 years his junior. That kind of result in a 235-man Masters field doesn't happen by accident. Lawrence Chiu, 4th in 22:21, added his own layer to the story: he had already raced the men's 5K on Saturday, finishing 10th there, and came back to crack the Masters top five the very next day. Racing hard across consecutive days at this level is no small thing.

Further down, the depth of the field held up well through the teens. Eric Hankinson and Ethan Lowry both clocked 26:49 to finish 16th and 17th respectively — separated by the timing mats rather than any meaningful gap. And Douglas Vetter, 67 years old and making the trip from Jackson, MS, ran 26:32 to finish 14th, a performance that quietly stands out in any field of 235.
