F30-34: Rozlyn Boutin Seizes the Lead and Never Lets Go

• Rozlyn Boutin, 2:46:57 (6:22/mi): Won the F30-34 field and moved to 1st among women by the second checkpoint — a lead she held for the remaining 20+ miles.
• Sylvie Abel's blazing open: Abel posted the 5th-fastest women's split on the opening 1.81–5.55 mile stretch and led the women's field through the first checkpoint before fading to 6th among women and 2nd in F30-34 at 2:59:17.
• Tight mid-pack cluster: Places 6 through 9 — Alexandra Gold (3:22:46), Elisa Polino (3:23:02), Steph Lee (3:23:05), and Lauren Roche (3:23:33) — were separated by just 47 seconds across four finishers.
• Late chargers: Kayla Kobelin (4th, 3:15:20) and Nicole Hood (5th, 3:19:58) both ran their way up through the field in the second half, with Kobelin posting the 8th-fastest women's split over the final mile-plus and Hood the 17th-fastest women's split across the entire second half.

Rozlyn Boutin, 31, from Vancouver, BC, delivered the dominant performance of the F30-34 field on a cool, humid San Francisco morning. Running a 6:22/mi average, she clocked 2:46:57 — a full 12 minutes and 20 seconds ahead of the runner-up — and did it with authority. She arrived at the second checkpoint already in 1st among women and never relinquished that position, while also recording the 2nd-fastest women's split on the 1.81–5.55 mile stretch to signal early that she meant business.

The early drama belonged to Sylvie Abel, 34, from Los Gatos, who blazed through the opening miles with the 5th-fastest women's split on that same early segment and briefly led the women's field. But the pace caught up with her — she slipped to 4th among women by the second checkpoint and continued to drift back, ultimately finishing in 2:59:17 at 6:50/mi. That's a genuinely fast marathon, but the gap to Boutin tells the story of two very different second halves.

Third place went to Mariana Davil, 32, from Juriquilla, in 3:03:49 (7:01/mi), who ran a measured race and cracked the 4th-fastest women's split on the 5.55–6.52 mile segment. Behind her, the race turned into a battle of attrition and late momentum. Kayla Kobelin, 31, from Bend, OR, was 33rd among women at the first checkpoint and clawed her way to 14th by the finish, earning 4th in F30-34 at 3:15:20 with one of the strongest closing splits in the field. Nicole Hood, 33, from Walnut Creek, made a similar move — 30th among women early, 22nd at the line — finishing 5th in 3:19:58. In a 354-finisher F30-34 field, the front of the race was decided early; the back half was all about who had the legs to move.
