San Francisco Half Marathon: Samantha Ybona Crosses the Finish Line

• Sole finisher: Samantha Ybona, 28, of Oakland, completed the San Francisco Half Marathon in 2:43:50 at a 12:30/mi average pace.
• Conditions: Cool and damp — 57°F with 91% humidity and overcast skies made for a challenging atmospheric backdrop.
• Mid-race movement: Ybona's position among women shifted from 798th to 867th, 971st, and ultimately 986th as the race progressed.

With just one finisher to speak of in this race, the story belongs entirely to Samantha Ybona — and it's a story worth telling. The 28-year-old from Oakland covered 13.1 miles through San Francisco's famously demanding streets in 2:43:50, averaging 12:30 per mile on a day that offered little mercy: thick humidity at 91% and a cool 57°F had the air feeling heavy from the gun.

Ybona's position among the women's field drifted back as the race wore on — 798th at the first checkpoint, 867th, then 971st, and settling at 986th by the finish — a reflection of the field's faster finishers pulling away over time rather than any dramatic fade on her part. On the 2.95-to-5-mile stretch, her split ranked among the slower efforts of the day in the women's field, but she kept moving through one of the most topographically punishing half marathons on the American road racing calendar.

Finishing a half marathon in San Francisco — with its notorious hills, coastal wind exposure, and the psychological weight of the course — is its own accomplishment. Ybona owned the finish line for this group, and that's a result no one can take away.
