Half Marathon NB45-49: Yi Seul Park Stands Alone

• Solo finisher: Yi Seul Park, 45, of Palo Alto, CA, completed the NB45-49 field with a time of 2:52:36 (13:10/mi).
• Consistent women's standing: Held 4th among women from the opening checkpoint through the finish line.
• Standout segment: Ran the 4th-fastest women's split on the 2.95M–5M stretch.

Yi Seul Park was the sole finisher in the NB45-49 field on a cool, humid San Francisco morning — 60°F and 86% humidity with a light breeze off the bay — crossing in 2:52:36 at a 13:10/mi pace. With no one else in the field to race against, the story here is entirely about how Park performed within the broader women's race, and that story has some real substance to it.

Park held 4th among women from the earliest checkpoint all the way to the finish — a steady, unwavering position that speaks to a consistent effort over the full course. No fading, no being passed, no late scramble: the same place at every marker.

The most telling number comes on the 2.95-mile to 5-mile segment, where Park posted the 4th-fastest women's split in the field. That stretch rewarded runners willing to push, and Park clearly did — running that leg faster than the vast majority of women on the course. It's the kind of mid-race move that doesn't always show up in a final time but tells you something real about how the race was run.

A finish of 2:52:36 over the hills of San Francisco, with a locked-in women's standing and a genuinely fast mid-race split — Park owned the NB45-49 field completely, and did it with authority across the broader women's race too.
