F20-29 Marathon: Eysenbach closes strong to claim the title

• Grace Eysenbach, 3:11:10 (7:17/mi): Won the F20-29 field, climbing from 27th to 14th among women in the second half with the 3rd-fastest women's split on the back half of the course.
• Razor-thin 3rd/4th: Jenica Seawell (3:16:20) and Haven Lambrite-Dodge (3:16:21) finished one second apart — 3rd and 4th in the F20-29 field.
• Charlotte Bourg surges: Starting 39th among women at the halfway mark, Bourg charged to 20th by the finish with the 16th-fastest women's back-half split, landing 5th in F20-29 at 3:17:27.
• 92 finishers competed in the F20-29 field on a flat, fast course through Sonoma County wine country — a natural setup for Boston Qualifier attempts.

Grace Eysenbach, 26, of Mountain View, made her move when it counted. She reached the halfway point sitting 27th among women, but her 3rd-fastest women's split on the 13.1M-to-finish stretch rewrote the leaderboard. She crossed in 3:11:10 at a 7:17/mi clip, climbing all the way to 14th among women overall and taking the F20-29 title by 49 seconds over Joanna Choi.

Choi, 29, of Los Angeles, was no slouch in the second half either. She moved from 23rd to 15th among women with the 6th-fastest women's back-half split, finishing in 3:11:59 at 7:19/mi. The gap between them is real — nearly a minute — but the story is that both women were running each other down through the field simultaneously, making the final standings a testament to two strong second halves.

Behind them, the race delivered one of the tightest finishes of the day: Rocklin's Jenica Seawell (3:16:20, 7:29/mi) and Fair Oaks' Haven Lambrite-Dodge (3:16:21, 7:29/mi) were separated by a single second at the line for 3rd and 4th. Seawell had the 20th-fastest women's back-half split, Lambrite-Dodge the 21st — both held their pace and neither gave an inch.

Charlotte Bourg, 29, of San Francisco, was the field's biggest mover, going from 39th among women at the halfway point to 20th by the finish, with the 16th-fastest women's split on the back half. Her 3:17:27 (7:32/mi) earned her 5th in the F20-29 field — a finish built entirely on second-half conviction.
