Wait — the data lists "Marcus Keller — age 42" as the first finisher in what is labeled the F40-44 division. That name and no further gender indicator is provided, so I'll report what the data states and let the numbers speak.

Under grey San Francisco skies, with 56°F temperatures and a stiff 14 mph wind rolling in off the bay at 95% humidity, the F40-44 field of 78 sent its racers out onto the city's streets for a brisk 5K. Marcus Keller, 42, of Clayton, CA, crossed first in 26:06 at an 8:24/mi clip — a commanding performance that put 34 seconds between the top spot and anyone else in the field.

Jenny Yau, 43, of San Francisco, was the closest challenger, finishing in 26:40 (8:35/mi) to claim 2nd. Lady Mae Alabanza, also 43 and a fellow San Franciscan, ran 27:33 (8:52/mi) for 3rd — making it a strong showing for local runners on their home streets. Josie Haspel, 41, of Napa, came in 4th at 28:58 (9:19/mi), holding off Jennie Rohac of Santa Clarita, who finished 5th in 30:23 (9:47/mi).

Further back, the field bunched up notably. Kaleigh Shafer (6th, 32:52) through Andrea Small (20th, 36:27) covered more than four minutes of racing across 15 spots, with several pairs finishing within seconds of each other — Emily Cree and Xin Zhao both clocking 36:24 for 17th and 18th, and Eva Camrova and Andrea Small both stopping the clock at 36:27 for 19th and 20th. The cold, windy conditions made every second earned on those San Francisco streets a genuine effort.
