Kimberly Arias of Davis, CA stepped onto the San Francisco streets on a cool, overcast July morning — 53°F, 95% humidity, and a 7 mph wind off the bay — and made the NB25-29 5K entirely her own. With a finish time of 42:18 at a 13:37/mi pace, she crossed the line as the sole finisher in her field, claiming an uncontested but no less real victory.

Racing a 5K through San Francisco is no formality. The city's terrain and that thick, heavy air demand something from every finisher, and Arias delivered hers. She gets the win, the top spot, and bragging rights for the NB25-29 field — all to herself.
