  • Corinna Schlatter, 1:27:23 (6:40/mi) — won the F1-17 field by nearly 12 minutes, climbing from 59th to 50th among women on the back half.
  • Esther Belusko (1:39:08) and Addison Max (1:45:05) completed a Saint Helena 1-2-3, with Belusko posting the 109th-fastest women's split on the 6.9M-to-finish stretch to hold off Max by nearly six minutes.
  • Audrey Schallon (1:48:13) ran the 140th-fastest women's split on the 3.1M–6.9M segment but faded in the second half, sliding from 161st to 234th among women — still good for 4th in the F1-17 field.
  • J. Langum, age 13 (2:04:37), was the youngest finisher in the top half of the field, crossing just 25 seconds behind 7th-place Tatum Smith (2:04:12).

Corinna Schlatter, 17, from Saint Helena, made this race her own from the opening miles. Running a 6:40/mi average, she finished in 1:27:23 — a margin of nearly 12 minutes over the rest of the F1-17 field. Her second half told the real story: she posted the 35th-fastest women's split on the 6.9M-to-finish stretch, moving from 59th to 50th among women in the process. In a field of 13, that kind of closing power is simply a different gear.

Behind her, Saint Helena produced one of the day's quiet storylines: three of the top three finishers hail from the same small Napa Valley town. Esther Belusko (15, Napa) took 2nd in 1:39:08, running a 7:34/mi average and closing strongly with the 109th-fastest women's split on the back half. Addison Max (16, Saint Helena) rounded out the podium in 1:45:05 at 8:01/mi, though she slid from 154th to 187th among women across the second segment — Belusko clearly the stronger closer of the two.

The middle of the field offered its own drama. Audrey Schallon (4th, 1:48:13) was sharp through the midpoint, running the 140th-fastest women's split from 3.1M to 6.9M, but faded to 234th among women by the finish. Nia Azarcon (5th, 1:52:48) ran the opposite arc — moving from 394th to 298th among women through the middle miles before settling at 324th, a notable charge through the field. Katherine Heil (6th, 1:59:08) and Tatum Smith (7th, 2:04:12) rounded out the top seven, with 13-year-old J. Langum (8th, 2:04:37) finishing just 25 seconds back — a composed run from the youngest finisher in the top half of the field.
