San Francisco Marathon Women's 25–29: Calamia Owns It from Gun to Tape

• Cal Calamia won the women's 25–29 field in 3:00:00 (6:52/mi), holding 1st among women from the very first checkpoint through the finish.
• Calamia posted the fastest women's split on the 2.2–5.7 mile segment, the sharpest early move in the women's field.
• Winter Watson finished 2nd in 4:07:20 (9:26/mi), climbing from 11th among women to 9th by the finish — picking off two places in the back half.
• Watson recorded the 5th-fastest women's split on the Garmin Hill Challenge segment, a strong showing on one of the race's signature tests.

The women's 25–29 field at the 2022 San Francisco Marathon came down to two athletes, and Cal Calamia made the outcome clear early. Racing in the cool, damp morning air — 54°F and 94% humidity with barely a breath of wind — Calamia locked in at 6:52/mi and never relinquished her lead among women. She sat 1st in the women's field at every single checkpoint, a wire-to-wire performance backed up by the fastest women's split on the 2.2–5.7 mile stretch.

Crossing in exactly 3:00:00, Calamia's finish is as clean as it gets on a demanding San Francisco course. That's a statement time on roads that offer precious few flat stretches.

Winter Watson ran a different kind of race. Starting 11th among women, she held steady through the middle miles before finding another gear late — moving to 10th and then 9th in the final segments. Her 5th-fastest women's split on the Garmin Hill Challenge showed she had real strength when the course tilted upward. She finished in 4:07:20 at 9:26/mi, 1:07:20 behind Calamia — but with a quiet late-race surge that earned her places in a larger women's field.
