SF Half Marathon F1-19: Brochu surges from the back to claim the title

• Maya Brochu, 1:30:08 (6:53/mi) — won the F1-19 race, climbing from 20th among women at the first checkpoint all the way to 2nd among women by the finish, with the fastest women's split on the 5.7M–6.43M segment.
• Elle Marsyla, 1:30:44 (6:55/mi) — runner-up, just 36 seconds back, posting the 3rd-fastest women's split on the 6.43M–8.3M stretch after running in the top 10 among women from the gun.
• Lyanne Wang, 1:44:00 (7:56/mi) — 3rd in F1-19, climbing steadily from 62nd among women at the first checkpoint to 36th by the finish.
• Nandini Neralagi, 1:48:35 (8:17/mi) — 5th in F1-19, started 8th among women but faded across the middle miles, a sharp contrast to the top two's upward trajectories.

The headline story in the F1-19 field belongs to Maya Brochu, a 17-year-old from Bow, NH, who ran one of the most dramatic charge-through-the-field races in the women's race. She was sitting 20th among women after the opening miles — hardly the position you'd expect from the eventual F1-19 winner — but she was methodically reeling in runners. By the midpoint she had crept into the top 10 among women, and she kept coming, reaching 5th, then 2nd among all women by the tape. The engine behind that surge: the fastest women's split on the 5.7M–6.43M segment, a burst that signaled she had found another gear while others were holding on.

Elle Marsyla of Woodside, CA ran a smarter, more front-loaded race — already 9th among women early and rising to 3rd by the midpoint — and answered with the 3rd-fastest women's split on the 6.43M–8.3M leg. She couldn't quite reel Brochu in, but her 1:30:44 at 6:55/mi made her the clear runner-up, 36 seconds behind. The two teenagers — both running sub-6:55 pace through a damp, cool San Francisco morning — put a significant gap on the rest of the F1-19 field; 3rd-place Lyanne Wang of Lafayette, CA finished in 1:44:00, a full 13:16 behind Marsyla.

Wang's own race had a quiet narrative: she was 62nd among women at the first split but worked her way up to 36th by the finish, good enough for 3rd in F1-19 at 7:56/mi. Behind her, Paige Unger (4th, 1:46:39) produced the 50th-fastest women's split on the 8.3M–11.45M segment — a strong late push that helped her hold off Neralagi, who faded from 8th among women early all the way to 75th by the finish. Abigail Porter (6th, 1:49:34) through Audrey Morrison (20th, 2:03:55) filled out a competitive young field of 40 runners who braved the Bay's signature chill to race 13.1 miles through one of the country's most demanding urban courses.
