San Francisco Half Marathon — F25-29: Corbett Runs Clear in a Loaded Field

• Victoria Corbett won F25-29 in 1:38:56 (7:33/mi), finishing more than 6:30 clear of the second-place runner in a 674-finisher field.
• Bella Kuo (2nd, 1:45:29), Grace Cho (3rd, 1:45:49), and Xi Zhang (4th, 1:45:58) were separated by just 29 seconds across three places — a fierce battle for the podium's lower steps.
• Katherine Westcott ran the most dramatic climb of the race, moving from 117th among women at the 2M mark all the way to 51st by the finish on the strength of the 40th-fastest second-half split in the women's field.
• Grace Cho posted the 35th-fastest women's split on the 4M→6M segment, the move that helped her edge past Kuo and Zhang for third.

Victoria Corbett, 26, from Burlington, ON, turned in a performance that simply belonged in a different conversation from the rest of the F25-29 field. Her 7:33/mi average produced a 1:38:56 finish — and while her position among women fluctuated through the middle miles, she was back to 8th among all women by the finish and never relinquished the F25-29 lead. Her 9th-fastest women's split on the 2M→4M stretch was an early signal that she was running at another level. The gap to second place wasn't a photo finish — it was a statement.

Behind her, the race for 2nd through 4th was genuinely gripping. Bella Kuo (1:45:29), Grace Cho (1:45:49), and Xi Zhang (1:45:58) traded places throughout. Kuo had the 40th-fastest women's split on 2M→4M and held her position into the final miles, while Cho made her decisive move on the 4M→6M segment — posting the 35th-fastest women's split there — to secure third. Zhang, also strong early, couldn't quite match Cho's mid-race surge and settled fourth at 1:45:58. Twenty-nine seconds covered all three.

Further back, Katherine Westcott authored the field's best comeback story. Starting outside the top 100 among women, she ground her way forward segment by segment, ultimately crossing in 1:47:20 (8:11/mi) for 5th in F25-29. Her 40th-fastest women's split on the back half was the engine of that charge. Amanda Wong (6th, 1:47:35), Christine Sih Chin Ng (7th, 1:47:41), and Olivia Rupprecht (8th, 1:47:44) finished in a tight cluster, with just nine seconds separating the three of them through the cool, breezy San Francisco morning.
