• Lluvia Vega Munoz (28:43) rounded out the top six, while a gap of nearly 1:31 separated her from 5th-place Matilda Samuels — the largest gap within the top ten.

The story at the front of the F0-19 race was a remarkable one: a 10-year-old from Rohnert Park outrunning a field full of older competitors. Maddie Guizar crossed in 26:34, averaging 8:33 per mile to claim the win. Right on her heels was 12-year-old Brooke Adams-Hopkins of Larchmont, NY, who finished in 26:42 — just 8 seconds back and pushing the pace hard at 8:36/mi. That Guizar held her off at age 10 is the headline performance of the morning.

The battle for the podium's third step was equally sharp. Natalya Fabela (27:12, 8:45/mi) and Alihna Diaz (27:16, 8:47/mi) ran nearly the entire race together, with Fabela edging ahead by 4 seconds. Right behind them, 11-year-old Matilda Samuels of Salinas closed out the top five in 27:21 — meaning five runners spanning ages 10 to 15 finished within 47 seconds of each other, making for a genuinely competitive front pack.

Further back, Lluvia Vega Munoz (28:43) and Faith Hernandez (30:14) held 6th and 7th, while Sarah Foster (30:51) and Zariah Khoury (31:41) — another 10-year-old — rounded out the top nine. Jhia Sambrano closed the listed top ten in 33:19. With 41 finishers in total and ages ranging from 10 to 19, the F0-19 field at Santa Rosa showed plenty of young racing talent on a cool, calm August morning.
