F19 & Under: Beaman and Sinclair Duel to the Wire in San Francisco

• Dead-even finish time, different stories: Bryn Beaman (1st, 3:29:28) and Katie Sinclair (2nd, 3:29:28) crossed the line in the same second, yet Beaman edged ahead by the finest of margins to claim the title.
• Beaman's mid-race surge: Beaman climbed from 174th among women at the start to 42nd by the finish — and posted the 6th-fastest women's split on the 10.89M→Garmin Hill Challenge segment, a key moment in her charge through the field.
• Sinclair's closing kick: Sinclair answered with the 11th-fastest women's split on the 24.69M→Finish stretch, nearly erasing Beaman's lead entirely — but "nearly" was the margin.
• A clear gap to third: Paige Yun (3rd, 3:35:50, 8:14/mi) finished over six minutes back, with Siwen Cui (4th, 3:40:26) and Alexandra Wong (5th, 3:42:48) rounding out the top five.

The headline story among the F19 & Under field at the 2024 San Francisco Marathon is one of the tightest finishes you'll see: Bryn Beaman of Roseville, CA, and Katie Sinclair of Palo Alto, CA, both clocked 3:29:28 — yet Beaman took the win. These were not identical races, though. Beaman came in as a charger, entering the women's field in 174th place early on and grinding her way up to 42nd by the tape, averaging 7:59/mi across 26.2 miles on a cool, fog-heavy San Francisco morning.

Sinclair's path was different but no less impressive. She tracked a steadier line through the women's field — 109th early, 43rd at the finish — and saved her best running for last. Her 11th-fastest women's split on the final stretch from 24.69 miles to the finish was a genuine closing surge, one that nearly caught Beaman entirely. The finish time was the same to the second; the place was not. Beaman held on.

Behind the top two, Paige Yun (3rd, 3:35:50) turned in a composed effort at 8:14/mi, posting the 34th-fastest women's split on the Garmin Hill Challenge segment. Siwen Cui had one of the most dramatic trajectories in the field — sitting 472nd among women early in the race before rocketing to 84th by the finish, backed by the 13th-fastest women's closing split. Alexandra Wong (5th, 3:42:48) and Maddie Barlow (6th, 3:46:33) completed a strong top six in a field of 39 finishers.
