  • Penelope Samuels, 13, wins in 41:29 — a 6:41/mi average that put her more than 11 minutes ahead of the rest of the 15-girl field.
  • Julia Eriksson and Kirsten Dunbar, both 11 years old, finished 4th and 5th in 1:01:43 and 1:01:55 respectively — just 12 seconds apart after 6.2 miles in the rain.
  • 13th and 14th place went to Tiger Ciampi and Shelby Salehieh, both clocking 1:31:19 at 14:42/mi — separated by a timing sliver, with Ciampi holding the edge.
  • Kattie Armenta, 18, rounded out the field in 15th with a 2:08:11 finish at 20:38/mi.

Penelope Samuels, just 13 years old and racing out of Salinas, turned in one of the most dominant performances in the F0-19 field on a cool, drizzly Santa Rosa morning. Her 41:29 finish at a 6:41/mi clip wasn't just a win — it was a statement, arriving more than 11 minutes before second-place Mila Hernandez (52:49, 8:30/mi). That gap of over 11 minutes across a 10K field of 15 tells you everything about how thoroughly Samuels controlled this race from wire to wire.

Behind Hernandez, 19-year-old Stephanie Pham crossed in 3rd at 59:54 — just sneaking under the hour mark at 9:38/mi. Then came a genuinely compelling battle between two 11-year-olds: Julia Eriksson of Santa Rosa (1:01:43) and Kirsten Dunbar of Willits (1:01:55). Twelve seconds separated them after more than six miles on wet roads — a close, hard-fought finish by any measure, and a remarkable showing for the youngest competitors in the field.

The middle of the pack saw a cluster of finishers between 1:08 and 1:10. Siena Escutia (6th, 1:08:08), Camila Dresser (7th, 1:08:29), Mikaela Punzalan (8th, 1:09:08), and Esmeralda Ramirez (9th, 1:09:52) were separated by less than two minutes across four places — tight enough to make that stretch of the race genuinely competitive. Karen Phan (10th, 1:18:23) and Hope Madden (11th, 1:24:35) followed, with Alexandra Tallon finishing 12th in 1:25:11. Tiger Ciampi and Shelby Salehieh shared the clock at 1:31:19 in 13th and 14th, with Ciampi holding the narrower edge by the timing system. Kattie Armenta, 18, completed the field in 2:08:11 — every finisher earning their result on a damp August morning in Sonoma County.
